Replacing the standard fuel filter from another machine. Where is and when to change the fuel filter

Replacing the fuel filter is a problem with which, for sure, each driver has come across. This element of the car eliminates the whole garbage, rust particles, dust and does not let them get into the highway fuel system. And since the components in it have a very small cross section, then the falling dirt would quickly lead them into disrepair.

When is it obvious that the fuel filter is needed?

The filtering system performs two degrees of purification: rough, removing all major particles, and thin. Installed between the engine and fuel tank. Experts advise the replacement of filters every 60 thousand kilometers. After all, their accuracy leads to very serious consequences, for example, an additional burden on the fuel pump arises, and it may fail much faster. Also, the clogging generates incorrect operation of the engine, because the fuel supply to the system does not occur as if it should.

Thus, the car reads troit, it stalls, and sometimes it may not start at all, and incorrect gear shift occurs (in the case of automatic transmission, i.e. automation ceases to correctly interpret the engine commands to switching and performs their inadvertent or reacts at all). But in order not to bring the situation to such a critical moment, you can check whether the fuel filter does not need. At low speed, sharply press the gas pedal, if the car does not accelerate either there are jerks, it means that the filter replacement is necessary.

How to change the fuel filter - buying a new element

When this item is selected, you must pay attention to the following parameters:

• filtration level. If it is insufficient, and large particles still penetrate into the system together with the fuel, it will very quickly lead to the engine breakdown;
• the area of \u200b\u200bthe filtering element, as well as the presence of a rubber seal, which covers the input to the filter itself. In the event that there is no one, this item will be very problematic to replace.

Depending on the fuel system, thin cleaning filters are divided into:

• carburetor, permissible degree of purification of 15-20 μm (particles of smaller size will be held in this system, but will not harm the fuel delivery system in the motor);
• injector, smaller degree of cleaning, 5-10 μm (in such systems requirements for maximum size Permissible contamination above, i.e. The injector can be clogged from larger particles, so the holes in the filter is less);
• diesel, capable of holding not only very small solid particles (less than 5 microns), but also to remove moisture, and this is very important for.

When buying it is important to specify the seller the brand and the year of release your car to choose the right filter. For the most part, if there was no product specifically for your case, you can choose something interchangeable. But there are cases when it is impossible, so familiarize yourself with this information in the manual for your transport facility.

How to replace the fuel filter - instruction for independent

Of course, you can contact the specialists who replace this detail for ten minutes. However, if you want to save a little, then make a similar procedure yourself quite real, and now we will tell you how to change the fuel filter. To do this, it is necessary to determine its location, most often it is under the hood, at the top of the engine (characteristic of diesel cars) But there are some models in which you can find it in a tank next to the fuel pump (this is a feature of gasoline cars).

Then you should pull out the fuse from the fuel pump and wait until the engine is stroke, so you hover the pressure and keep yourself from pouring fuel. Now turn off the negative terminal of the battery, in order not to be marked, and carefully examine the method of attaching the old fifteer to the fuel line (intake mount and graduation), it can be baratic bolts, and latches, the main thing is to remember, in which sequence everything was in order to also establish and new element. Mark visually and location of sealing washers and rubber gaskets.

Now wander old filter Rafting, so as not to flow fuel, and remove it, after removing the bracket, which supports it in a bunch with a top-core. Install new detail At the bracket exactly in the same position, in which the old one was located (sometimes on the filter you can find a tip in the form of a shooter, how to insert it into the nest). With the help of new fasteners (they are included in the kit), connect the fuel line, after checking the integrity of all its lines, in case of detection of a defect (cracks, inflection) it is necessary to replace it.

It remains to insert the fuel pump fuse, connect the terminal and start the engine, it does not always work from the first time, since the pressure was lowered. In the question, how to replace the fuel filter, the safety technique should be very much attention. If you smoke, then give up this harmful habit while working. Make sure that the room is well ventilated, and do not forget to thoroughly wash off the fuel from the skin of the hands. Also, would not hurt just in case stocking and fire extinguisher.

Welcome!
Fuel filter, and what is it? And why is it needed? And what will happen to the car if he is clogged? And how to replace it? These questions ask very often car owners who are very interested to learn about the structure of their car and the aggregates that are installed on it. If you are the very avid car owner, then we will try to reveal a few questions that relate to the fuel filter.

Note!
If you know something about these filters and want to add information, then, in this case, leave your comments at the bottom of the site and people will see them!

Summary:

What is a fuel filter?
In their form, he resembles a closed small jar, on which on the one hand there is a tube, and on the other too. (This concerns injector cars)

And what about the carburetor, then in its form the filter is completely different in contrast to injector filter. On the carburetor filter is mostly glass that protects the filter from getting into it the dirt is transparent, due to this, it can be easily understood when the filter is clogged and will need to be replaced.

Why do you need a fuel filter?
From the very name, you can already understand the purpose of this unit. The filter serves to purify the fuel from dust and from other small particles that fall into the engine from the gas tank car.

At the moment, the fuel filter is present in different systems, the main of which is a carburetor, an injector, as well as diesel. For more information, the filter is in all three systems, look just below:

In the carburetor - the fuel filter is designed to protect the buses from dust, as well as other small particles. Because how many people are already known if the jets in the carburetor will be clogged, then the first thing this will lead to the fact that the power of the motor will decrease.

In the injector, the fuel filter serves to protect the nozzles from dust and from other particles that will clog them, which in turn again will lead to incorrect operation of the engine and to the power decline.

In a diesel engine, diesel cars are almost the most demanding of the fuel purity, so in such cars, as a rule, two fuel filters are usually worth it, one of which is a coarse filter, and the other fuel purification filter.

How will the car behave if the fuel filter is clogged?
Usually the following actions occur with the machine:

1. First, as a rule, when clogged the filter, the car will begin to twitch when lifting up the mountain or with normal driving on the car.
2. It may be added to all this, the explicit deterioration in the power of the car is because the filter can no longer clean gasoline from dust and from water that is present in gasoline.
3. Can still be added increased flow Gasoline, and the car when moving can simply sall.

Replacing the fuel filter:

The fuel filter is one of the mandatory fuel supply nodes. It is inside the fuel filter that the fuel is separated from the fuel of a variety of suspensions that can have a negative impact on the operation of the engine.

And if the filter did not stand, all this smallest dirt would gradually accumulated inside the engine, settled in the most unexpected places. And gradually the engine would have spent its resource not only to move the car, but also to overcome the friction on these sediments. In addition, all fuel lines, channels in the carburetor, holes in the nozzles would be clogged with mud.

But it is thanks to the filter dirt remains on the surface of the filter elements and does not fall into the engine system. And the engine works normally until the filter elements pass fuel in the desired engine Dosage. But as soon as the transmittance of the filter deteriorates, it immediately affects the operating characteristics of the engine. And the question arises: how to change the fuel filter?

Signs of the need to replace the fuel filter

Signs that the engine needs a filter replacement, a lot. And these signs often coincide with the manifestations of other problems. But still, you can select a few moments, which will be given a signal that the fuel filter replacement is required. Namely:

• the engine begins to start badly, but at the same time normal spark and all systems work normally;
• during operation, the engine begins to sneeze, tall. Stable work the engine is not observed;
• there is a reduction in engine power;
• increases, and constantly, fuel consumption consumption;
• on the rise begins problems with the drop in power and with the engine operation. The engine can dwell on the rise;
• there are significant problems with the operation of the engine at idle.

The frequency of replacing the fuel filter according to the instructions

Usually, the instructions for the car contains data on the frequency of the fuel filter replacement. But it must be borne in mind that this figure is very conditional, and some nuances associated with fuel quality on domestic fuel gas stations are unaccounted in it.

The fuel at refueling can be of the most different quality, and the bay of gasoline several times in unknown refills, you can easily get clogging the fuel filter, so to speak, outside the graph. And if after several refills, there are problems with the engine, which are described above, it makes no sense to expect when the full-time operation of the fuel filter will expire, and to replace it as quickly as possible. Otherwise, the problems will only be aggravated, and not only the fuel system, but also other systems and knots of the car may suffer. In the middle, the fuel filter should be changed simultaneously with the replacement oil filter. Every 10,000 kilometers.

How to replace the fuel filter with your own hands

Replacing the fuel filter with your own hands - not too complicated technical task. To replace the filter, you need a minimum number of tools and minimal technical knowledge.

It is not always possible to change the fuel filter without dismantling, for example, a battery or some other node on the car. But as soon as free access to the fuel filter is provided, further operations should not cause special difficulties.

It is advisable to do all this in protective gloves and perhaps even need safety glasses, as fuel or condensate can be sprinkled. Mass on the car must be disabled.

The fastening system of fuel pipes can be completely different, and in each case, before dischairing the tubes that come from the fuel filter, you need to carefully examine the fastening system. In any case, it will be necessary to release something or unscrew. At the same time, you do not need to apply great efforts to accidentally do not ride the slot or face. And after the mount is weakened, you need to carefully pull the pipe from the attachment. In this case, you can scroll a little and again, do not make maximum efforts to not break the hoses.

After the old fuel filter is removed, you need to install it new filter And most likely, you will have to change the clamps if just such a fastening system is used to the fuel filter. Usually in the clamps there is a splitting of the slots during unscrewing. And when repeated tightening, you can not sufficiently press the connection site.

It is important to understand where the incoming nozzle, and where the emerging. On the filter housing, the arrow, which shows which way the fuel should move. And if you confuse, the filter will work incorrectly.

When clamping the clamps, you do not need to try to press as much as possible. This can lead to deformation of connecting nodes. After installing the filter, it does not make sense to immediately close the hood cover. You must first start the engine and see if there is no fuel leaks on the connecting places. The slightest appearance of fuel on the connecting places means one - the connecting elements must be pulled up to the moment the slightest manifestations of the leaks will disappear. And only after that you can close the hood and operate the car.

What threatens the late replacement of the fuel filter?

The late replacement of the fuel filter can lead to the fact that many engine nodes will work on wear. First of all, the fuel pump will suffer, which will be forced to pierce contaminated filter elements by increasing the pressure.

The process of starting the car will be difficult, which means that the starter will work in time more than necessary. And this is the wear of the teeth on the leading gear of the starter. The engine will constantly work in fasting mode, as fuel will constantly miss.

It will be faster to sit the battery, as she has to rotate the starter and flywheel longer. And ultimately all this will affect the resource rechargeable battery. And at one fine moment the car engine simply does not start. And the fault will be a polluted fuel filter. So on time made the fuel filter replacement - the correct step that allows you to avoid further problems.

The quality of the engine depends on many factors, and the purity of the combustion chamber of the fuel entering the chamber is one of the most students. For this, filters are built into fuel systems of all cars. Moreover, for varying degrees of cleaning. They are also called coarse and fine fuel purification. And any filter clogs, requires replacement. And the motorist is useful to know how to replace the fuel filter.

Rough Cleaning

The first fuel system is a coarse filter. It is located directly in the tank. Right on the fuel intake. It is usually a mesh formation of various shapes. From the grid with a shallow cell unable to skip garbage.

For carburetor machines

It is worn on a fence tubular pipe cone design made of fine metal mesh. Dress Usually without replacement, but only sometimes is washed.

For cars with "Injector"

Here the question is more serious. Fuel injection on these cars occurs through fuel injectors - Injectors. The diameter of the bandwidths is very small. Therefore, the danger of pollution is much higher than that of carburetor, and the possibility of washing is much lower. Accordingly, the protection of fuel filters is much stronger. The feature of the fuel system of "injection" machines is that the pump is either directly in the tank or right next to it. Now practically 100% of machines - with a pump inside the fuel tank. The filter on them is made of plastics and is attached directly to the pump. Not cleaner and does not wash. These filters are only replaced. The replacement scheme is approximately the same for all models. Even with different forms of the fuel filter itself.

Thin cleaning

Or in other words - sump. Designed to clean the fuel from the finest garbage and impurities of water by overflow from one capacitive cavity to another through a paper or other filler.

On cars with a carburetor, a fuel filter of fine cleaning is near the motor in front of the fuel pump. This is a plastic, transparent cup with two nozzles. Intake and prom

On the injectors, this is a metallic barrel with a diameter of about 12 centimeters and up to 20 long. In the end parts are fittings of the input and exit. Their two types. There is a threaded version of turnkey 19-17, and a new sample with tubes under the latch. Each filter is necessarily marked by an arrow of the fuel movement.

Important! Be sure to make sure proper installation Fuel movement filter. Otherwise, after 5-7 hours of work, the filter will lose bandwidth.

There is a fine cleaning filter from cars with ECM, as a rule, under the bottom near the fuel tank, less often under the hood. In Russian cars can be divided like this:

• VAZ (classic and SUVs) - under the hood;
• VAZ (front-wheel drive) under the bottom in the gas tank area;
• Gas.Uaz - under the hood.

Replacement on carburetor models

Replacing the filters of both types on carburetor models does not represent any complexity. Does not require special tools and skills. In order to replace the fuel filter-sump on a carburetor model, one is enough. The filter is fastened with conventional protracted clamps, put on fuel pipes. It is necessary to weaken the clamps and remove the hoses from the filter inputs. Everything can be replaced with a new one.

With a fuel filter of rough cleaning a little more complicated, if it is a front-wheel drive model:

• VAZ 2109;
• VAZ 2108;
• VAZ 2110;
• VAZ 2114.

Also modifications, then for the replacement will have to remove the back seat. Under it in the floor, there is a hatch, which is fastened with two screws in curly scold. After removing the hatch cover, you can access the built-in in fuel tank Fuel level sensor. There is also a suction nozzle with a filter. By revealing the six nuts, you can remove the module with a nozzle and rinse or replace the filter.

On classic cars with rear-driven

• VAZ 2101;
• VAZ 2103;
• VAZ 2106;
• VAZ 2107,

the fuel tank is in the trunk under the decorative panel on the right. There is even easier access. Remove the decorative casing with a tank and replace.

Attention! On the models of VAZ 2102 and 2104, the access hatch is in the floor luggage compartment left!

Replacement by car with Esud

Due to the features of the fuel system of "injection" machines, fuel filtering, therefore, the replacement of fuel filters plays a very important role. In addition, and their replacement is more complicated than on carburetor cars. This is due to the need to maintain a constant pressure fuel supply system from 2.5 to 3.5 MPa. For this everywhere, either threaded, or naval compounds on snags are used.

This guarantees the lack of fuel leakage. And facilitates the process of replacing the system nodes.

How to Replace Fuel Cleaning Filter

First of all, you need to lower the pressure in the fuel ramp. It is on the engine and combines all the nozzles into one block. At Ramp, or next to it, there is a special connector. It serves to connect a pressure gauge measuring fuel pressure. It is made in the form of a valve. Through this valve and conveniently reset surplus. After that, you can replace the filter. With any placement of the fuel filter, it is fastened to the body with a tightened bolt to 10. If the fitting of the filter is threaded, then you will need two wrenches with dimensions by 19 and 17. Not vacating the bracket to weaken the tightening of fittings and unscrew them completely. Release the fixture bracket, replace the filter-sump and fasten everything into place.

Important! Be sure to check the condition of the sealing rings on the tubes of the fuel line. Usually, in the kit immediately there are new, and it is better to replace them.

Carefully check the tightening in order to avoid leaks.

Replacing the fuel filter in the tank

This is the thinnest and difficult from the work of this type. The fact is that at most models, this filter is installed directly on the fuel pump, and the one, in turn, in a special fuel module. As a rule, the fuel module is made of gas resistant plastic. Therefore, when replacing, handle it should be carefully.

Most. simple device The fuel module for cars VAZ engine volume is 1.5 cubic meters. See the most difficult on the device and fixture the latest VAZ models - "Kalina", "Priora" and others.

It is enough to replace this filter on the front-wheel drive machines of the VAZ 2105 and 07. In order to pull out the device from the tank, you must at least shift the tank to 20 cm away from the wing. After that, with two keys to 17 unscrew the intake-exhaust fittings and disconnect the gas station control zhgut and the sensor. Head at 7 with a gate to unscrew eight fasteners. Gently remove the module. The pump is mounted on a long rod that gets up to the bottom of the tank. Replace the filter and install the module in place. When you set to check the state of the sealing gum on the hole for the module. Collect in reverse order.

ATTENTION: When unscrewing fuel fittings, be sure to mark them with chalk or tape not to confuse.

Front drive 1.5 l and 1.6 l

As in the carburette models, the observation hatch is located under rear seat.

On machines with an engine of 1.5 liters, the fuel pump module is metallic and open. It is enough to raise the seat, unscrew the hatch cover, turn off the harness, unscrew the metal fuel fifth fittings and unscrew the eight nuts in a circle from the clamping ring.

You can remove the module. We only need to carefully examine and, if necessary, replace the seal. In the lower part there is a removable glass. He is removed without effort. The fuel pump with fuel filter is fixed below it. Replace the filter and collect in the reverse order.

On cars with an engine 1.6 liters, plastic pipes and are attached with zags. Remove latches and fueling. Also unscrew eight nuts, turn off the wiring and pull the module. The module is made of plastic. The lower part, a glass is fixed with the top with the ring on the metal support tube. Remove the hairpin and disseminate the logging tube. Lock the fastening of the level sensor with a float. The glass will go down. Inside the pump is in a special nest on three stars. Move them and remove the glass. All, you can change the filter and collect in the reverse order.

On the new models of VAZ bolted module module is absent. It is held in a gas tank hole with a special clamping structure of a round form, which includes special protrusions and clamps. Quite witty solution. To replace you need tapping a hammer on special protrusions, turn fasteners.

In many foreign cars, this question is solved even easier. A rejected cover is made. Although its reliability is lower than that of the Russian version, the replacement is faster.

Fuel filter replacement frequency

The frequency of replacing the fuel filter for carburetors and "injectors is somewhat different. Usually replacing the fuel filter of fine cleaning for the carburetor is recommended by 50 thousand km. At the same time, the injectors recommended the frequency at least 30 thousand, and better than 20 thousand. If on carburetious, coarse filter often stands to the end of the life of the car, and they do not remember about it, then there should be no less frequency on Esud than 50 thousand ., Better than 30 thousand. This is a technological periodicity of replacement that does not take into account force majeure cases requiring urgent replacement of filters.

On the video, you can see the process of replacing the mesh for cleaning the fuel to "Lada Kalina":

How often it is necessary to change the fuel filter is indicated in the manual to the car. In this case, it is necessary to take into account that the frequency of replacement of the specified filtering device is designed without taking into account the quality of combustible and operating conditions of the machine. Therefore, there are situations where you need to change the filtering device before the deadlines recommended by the manufacturer of the machine.

Inspection units used to filter fuel

Why change the fuel filter? The main purpose of the fuel filter is the filtering of the particles of dirt, dust from fuel, to prevent them in penetration into the fuel system of the power unit. For undime replacement The specified filtering device is possible to clog the fuel supply system and the output of the auto motor.

For engines working on gasoline, two degrees of fuel purification. Diesel motors more sensitive to quality fuel mixesTherefore, for them, as a rule, three degrees of cleaning are used. For Motors, working on Dt, in winter, filtering devices with heating are used. In the presence of paraffin particles, the heating element prevents its crystallization and protects it, thus, the system from clogging.

Discern collapsible and unintended filtering devices. In the first embodiment, when the filter exits, it is made from the working state. full replacement. In the second variant, only the filter material can be changed - it is much cheaper than installing a new filtering unit.

Masters recommend changing the fuel filtering device after 30 thousand mileage kilometers. If there is a manual to the car, then you need to take 10 thousand kilometers from the period specified by the manufacturer. This will allow to take into account the domestic road domestic roads and the quality of the fuel sold at refueling.

Machine faults indicating the need to replace the fuel filter:

• vehicle is badly started while driving force aggregate begins to "troit";
• the capacity of the car decreased;
• increased fuel consumption;
• the automatic box switches the speed not on time or does not respond at all to the engine commands;
• on small revolutions harsh pressed On the gas pedal, the car is not gaining momentum at all.

Ignoring the above faults can lead to the output of the nozzles or the engine. Note, the specified symptoms may be observed at other faults: broken fuel pump or clogged air filter.

Select the filter unit correctly

Filtering device in a plastic housing for fine fuel purification

The filter parameters must comply with the requirements of the vehicle manufacturer, the deviation from the recommended indicators will deteriorate the engine and output of the fuel supply system.

When buying a device for filtering, pay attention to such characteristics:

1. Degree of filtering. For insufficient level Filtering Large particles can penetrate inside the auto motor and harm it elements - it will turn into a motor overhaul.
2. Filtering area. Insufficient area will lead to a decrease in the power of the machine, interruptions in the operation of the motor.
3. Quality of rubber seals. Poor-quality seals will allow to penetrate larger particles in the engine.
4. The system for which the device is selected:

• carburetor, degree of cleaning up to 20 microns, smaller particles will not harm the system;
• injector, implies filtering up to 10 microns;
• diesel, filtration of particles is less than 5 microns, and water from fuel is removed.

Buying a filter, specify the seller model and year of car release, it is important that the acquired device corresponds to the parameters necessary specifically by your machine. The resource of the motor and the fuel system will depend on the quality of the acquired device, so require quality certificates for the assembly of interest and do not buy products of dubious production.

Repair work

Arrogo, on the filter unit housing, indicating the direction of flow

In most gasoline cars, the fuel filter is between the fuel pump and the fuel tank, also the specified device can be built into the fuel tank. For diesel cars, a podcast arrangement (at the top of the motor) of the specified filtering device is characteristic. When performing dismantling and installation work on installing a new filtering device, observe such safety measures:

• repairing the fuel system, refuse smoking;
• perform repair work On the street or in a well-ventilated room - this will avoid the accumulation of fuel vapor;
• if fuel fell on the skin, rush it with warm water with soap;
• take care, so that there is a fire extinguisher near the workplace.

Replace the fine cleaning filter having a plastic case by following the following steps:

1. Unscrew the clamps fixing the incoming and outgoing fuel supply hoses, for this use a screwdriver.
2. Turn the clamps in the direction from the filtering device.
3. Disconnect one of the hoses and quickly get it up above the filtering device. These actions will help reduce fuel loss.
4. Secure the hose dropped and remove the second one.
5. Take a new filter, look at the arrow on its enclosure, it indicates the direction of movement of the fuel mixture. Install the filter unit according to the direction, put on the hoses and clamps on the legs of the filtering device and hold them.
6. Perform the fuel swap manual or by an electric pump.
7. See whether the liquid in the places of fastening of the clamps and the filter housing proceeds.

Replacement of non-separable filters

Change of unsolved filters on different types Auto runs in the following sequence:

1. Remove the fuse fuel pump, wait until the motor stops working. Thus, the pressure in the system is reduced.
2. Remove minus storm with battery.
3. Look at the method of fastening the filtering device. If the filter is fixed to the fuel pump, remember its position so that the new filtering element is in the same way. You can use the phone with the camera to simplify the specified task. Pay attention to the installation sites of sealing rubber and gaskets.
4. Take the rag and wrap the filtering device with it, because when it is disassembling a certain amount of fuel. Disconnect the filtering element from the mounting points to do this, use a screwdriver or wrench, the selection of tools depends on the method of fastening the device. Erase escaped fuel with car elements.
5. Install the new filter on the installation site of the old filter element. Pay attention to the arrow drawn on the body of the device, it indicates the direction of the fuel mixture.
6. Perform a fuel pipeline connection (pre-check its integrity, if necessary, replace the nozzle with the new one).
7. Place the fuel pump fuse.
8. Connect the battery terminals.
9. Get the car, let the engine work for a few minutes.
10. Check if there are leaks in the places of fastening a new filtering device.

After installing a new filtering unit, the machine can start from the first time. This situation may be caused by low pressure in the system. You can solve the specified problem with an ignition for one minute, after which you can try to start the car again.

Conclusion

Change the fuel filter at home. It is necessary to comply with security measures, as well as replace the filtering device in a strictly sequence. Note: the operation of the fuel system and the auto motor depends on the filtering unit selected for specific model Auto. The use of inappropriate according to the characteristics of the filter element will lead to a violation of the fuel and motor supply system.
