The fuel filter is used to clean the fuel from impurities and various contaminants that enter the tank when refueling a car. This is a mandatory part on both carburetor and injection VAZ models, so the owners of such cars should definitely study their features and methods of replacement.
Which fuel filter to choose?
Modification of filters depends on the engine size of the car. For the VAZ 2114, the engine size is 1.5 liters. Because the fuel filter in it is on hexagonal twists. For VAZ vehicles with an engine capacity of 1.6 liters, the filter is mounted on plastic rivets and has a spring retainer. Models with such a volume are injection, with direct fuel injection.
The VAZ 2114 car is a relatively new model, but its fuel system is no different from others. The filter should be replaced once every 10,000 km. At the same time, the VAZ car manufacturer recommends performing this procedure once every 25,000 km. Fuel filter contamination depends on the quality of gasoline that you use for refueling. The higher the octane number in gasoline, the less dirt it contains.. Therefore, you should not save on high-quality fuel.
The use of bad gasoline not only pollutes the cleaning devices - poorly cleaned fuel enters the injector, where deposits form on the fuel injectors. As a result, you will have to go to the service station and do a complete cleaning of the injector. There are several signs that indicate that it is time to change the fuel filter in a VAZ 2114 car. These symptoms are also characteristic of other cars.
So let's get started:
- While driving, there may be a significantly increased fuel consumption, this is due to the uneven flow of fuel into the VAZ 2114 injector.
- The car idles intermittently, the revs on the tachometer jump.
- Starting the engine is difficult, while it starts to troit.
All these reasons indicate that it is necessary to replace the fuel filter.
How to replace the filter?
You can buy a fuel filter for a VAZ 2114 in almost every car shop, but you should not save on the quality of the filter. Before buying, look very carefully whether the selected part fits your VAZ model, because they differ not only in threaded connections, but also in their shape and size. If the filter is larger, it will not fit into the retainer, and the direction of the fuel pipes will not match. If less, it will hang out.
You can replace the purchased part at a specialized car service or by yourself, which will not be difficult. To make a replacement yourself, in addition to the filter, you need an inspection hole or a hydraulic lift. During the replacement process, you will need a pair of keys for 10 and 12, as well as a Phillips screwdriver. The fuel filter in a VAZ 2114 car is located in the rear of the car in the middle of the fuel tank.
Before starting all work, you must remove the negative terminal on the battery. After that, it is necessary to relieve the pressure in the fuel tube. There are two ways to do this: you can relieve the pressure by pushing the nipple in the fuel rail of the injector, or by slowly depressing the locknut. In both cases, there will be a characteristic release of fuel, so do not neglect safety precautions when performing these works.
For further removal of the filter, it is best to apply the chemical WD-40, because your threaded connections are most likely corroded and hardened. Unscrew the part carefully so as not to strip the threads on the connections. After that, you can unscrew the latch and remove it completely. When removing parts, it is recommended to substitute a container to collect the escaping fuel (any bottle will do).
Installation of the part - what you need to know?
For cars with an engine capacity of 1.5 liters, the arrow will point to the fuel supply from left to right, for cars with an engine capacity of 1.6 liters, vice versa - from right to left. If you mix up the direction, the car will not work, and the fuel pump may burn out.
It is worth noting that it is much easier and more convenient to produce in cars with an injector, because they completely lack threaded connections. When replacing the filter on a VAZ 2114, it is necessary to change the rubber gaskets on the fuel supply pipes. They are supplied with the device. After completing all the procedures, you need to turn the ignition key for a few seconds so that the fuel pump has time to pump the required amount of fuel into the system. Next, look at the threaded connections - there should not be any traces of fuel on them.
The fuel filter must be changed after the car has traveled 20-30 thousand kilometers, provided that the fuel you are refueling with is of good quality. We, or rather our gas stations, have problems with this, to put it mildly, so the replacement of the VAZ 2110 fuel filter should be done much earlier than the regulated date.
Sometimes it is necessary to change the fine filter due to problems in the engine. Jerks while driving and unstable idle may indicate a critical contamination of the fuel filter.
In order for the 2110, you need several standard keys ("17", "19", WD-40 fluid, a small container for fuel that can pour out when the filter is turned off) and half an hour of free time.
How to replace the VAZ 2110 fuel filter with your own hands - step by step guide
1. Some motorists ignore or simply do not know about this item, however, it allows you to more accurately replace the fuel filter. I strongly recommend that before removing the fine filter, reduce the pressure in the fuel line, this is done as follows. It is necessary to remove the fuse responsible for the fuel pump, then start the engine and let it run until it stalls.
2. The VAZ fuel filter is replaced at a viewing hole or a lift. First of all, you need to find a fine filter, it is a small cylinder and is located under the car, in the area of \u200b\u200bthe beam and is attached to the bottom with clamps. (see photo) There are two fuel lines attached to it, so you can easily find it.
3. Take the previously prepared container and place it under in case there is fuel left in the system.
4. Now you need to get the filter, this is done using the keys on "17" and "19". Clean the connections from dirt and dust, if necessary, treat with a "WD-shkoy", then unscrew the fuel line fittings, as well as the filter clamp mounting bolt and remove the old filter.
5. After the old filter is unscrewed, it can be disposed of. When installing a new filter, pay attention to the arrows that are on the fine filter housing, they should be directed from the tank to the engine.
6. Tighten the union nuts and check the tightness of the connections.
7. Replace the fuel pump fuse and start the engine. While the engine is running, check for fuel leaks in the fuel line.
How to replace the fine filter VAZ 2110 video:
On the VAZ 2112, replacing the fuel filter is always a responsible procedure. First of all, this is due to the fact that the owner of the car does not know which filter is better to put.
The quick replacement of the 2112 VAZ fuel filter, of course, is due to the quality of today's gasoline too. But still, if the filter is the best, its service life is much longer.
General view
It is necessary to change this very filter on time, because if this is not done, then the negative consequences will directly affect the reliability of the entire car. First, let's find out what are the features and which one is better to choose.
Today there are many varieties of fuel filters: for carburetor and injection engines:
- If the filter is designed for a carburetor system, then its location is between the tank and the carburetor itself. Thus, the good location of this element prevents clogging of the carburetor jets with various debris, which is present in large quantities in modern fuel.
- In this case, as on the VAZ 2112, the filter will be under the car. As for injection systems, which are much more sensitive to pollution, compared to carburetor systems, the filter here needs to be changed faster.
Note. It is recommended to change this very element every 30 thousand kilometers of the car. But this applies only to those cases when high-quality gasoline is used. In view of the fact that today it is impossible to be 100 percent sure of the quality of Russian fuel, the filter must be changed every 20 or even 10 thousand kilometers.
It is no secret that some motorists, mostly beginners, do not even realize that this filter needs to be replaced. They continue to drive and on one protection of the fuel system reach 100 thousand km, or even more.
And in the end, they constantly complain that the car does not pull, it is not the same as before, the VAZ 2112 is not a car, and the like. And it was only necessary to replace the filter when it was necessary and there would be no such problems.
Here is an incomplete list of problems that arise if the filter is not replaced on time:
- a loss ;
- bad plant, in winter, in summer;
- extra load on the fuel pump, which starts to work in double strength, etc.
Knowing how to choose a good filter is an art. Here you need to take into account many parameters, but one thing is for sure: the quality of the paper is of no small importance.
Note. Experts advise dismantling the old filter, sawing it and examining the contents. So it will be possible to create the correct idea of what and how is inside.
If there is no desire to disassemble the filter, then you can listen to other motorists who prefer one filter or another. It will be useful to visit various forums where the pros and cons of one or another manufacturer are discussed.
Evaluation of modern filters for the injection system
If earlier, when there were carburetors under the hood of domestic cars, there were no such requirements for the fuel filter, today, with the advent of injectors (see), everything has changed. The new power system, implying injection, the creation is gentle and fastidious.
Give her the very best, and coarse gasoline won't make her feel good. And what is there fuel, injectors do not tolerate dirty air, and it must be clean.
Review
So:
- The best, according to many motorists, for the VAZ 2112 will be filters from Bosh. Why are they better than the rest?
According to experts, these filters will perfectly protect the entire fuel system not only from solid or water particles, but also from impurities that live in modern gasoline.
- In second place are Champion filters. They are available not only for gasoline versions of cars, but also for diesel ones. The ultra-efficient level of filtration of impurities and contaminants, the elimination of foreign particles and other advantages distinguish this Belgian filter from the mass of others.
- Mann filter manufacturers guarantee the perfect purity of the fuel that enters your car's system. They reliably protect the injection mechanism of the injector, removing various impurities and contaminants from the fuel. Dust, rust, and water will never get past this guardian.
- The filter that the majority of Russians voted for. This is Nipparts, which produces mostly spare parts for Japanese and Korean cars.
Today, the fuel filters of this well-known manufacturer are not the last in the list of the best in Europe.
Replacement
The above information has been provided to help you choose a good filter that is reliable and efficient. You no longer have to worry about contamination of the fuel system of your car, although you still need to change this filter after a certain time. Now we will learn how to replace the filter.
detailed instructions
So:
- So, first of all, you need to de-energize the battery.
- Then, holding the fuel filter with a wrench, unscrew the fitting with another wrench.
Note. At this point, you will need to substitute some kind of container under the fitting so that gasoline does not simply spill onto the ground.
- The second fitting is subjected to a similar dismantling.
- Now you need to loosen the clamp holding the filter. We use the key for 10.
- We remove the filter.
- We put a new one.
Note. When installing a new filter, you need to follow the arrow marked on the housing. This very arrow should be directed in the direction of fuel movement, that is, look at the left side of the VAZ 2112.
After installing a new filter, it is recommended to check the tightness of all connections by doing this manipulation with the engine running.
In the process of installing the filter with your own hands according to the instructions, it is also recommended to study photo and video materials. The price for such services in services today is very high. For this reason, learning how to carry out this operation on your own will be as relevant as possible.
The fuel filter is designed to clean the fuel from dirt and is a consumable item. The fastening of the nozzles to the fuel filter differs depending on the engine: the fuel filter for the 1.5 liter engine has a hexagonal mount, for the 1.6 liter engine it has a spring retainer.
How often to change the fuel filter?
There is no single answer to the question of when to change the fuel filter. The plant recommends replacing the fuel filter every 30,000 km. mileage, but in reality everything is completely different: a lot depends on the quality of gasoline, and you need to look not at the mileage, but at the signs of contamination of the fuel filter.
Signs of a contaminated fuel filter
If you are experiencing any of the following symptoms, then your fuel filter may be clogged and need to be replaced.
- Increased fuel consumption ().
- Unstable idle.
- Crashes on revs.
- Bad engine start.
- engine.
In addition to the fuel filter, these signs also indicate a malfunction of the following elements:, , , . So, when replacing the fuel filter, keep this in mind.
Where is the fuel filter located?
To find out where the fuel filter is, we need a flyover or a pit. The filter is located on the bottom of the car under a luggage carrier.
How to replace the fuel filter?
What we need to replace:
- fuel filter;
- sealing rings;
- keys for 10, 17, 19;
- empty clean gasoline container.
Removing the old filter
- Relieve pressure from the fuel line:
- We process the filter mount with penetrating lubricant (wd-40) if you have a 2111 1.5l engine.
- We take the keys for 17 and 19. With one we keep the filter from rotating, with the other we remove the fitting of the fuel supply line.
- We take an empty container with a volume of 0.5 liters and pour out the remaining gasoline from the fuel line.
- Unscrew the fuel outlet fitting.
- Disconnect the fuel line tubes from the filter and use a 10 key to unscrew the fuel filter coupling bolt.
With a 1.6l engine fuel filter, everything is much simpler - remove the fuel line tubes from the filter by pressing the fuel line clamps.
Fuel filter installation
- First of all, we change the o-rings at the ends of the fuel pipes.
- Install the filter in reverse order.
The only thing to consider is the direction of the filter. An arrow is installed on the gasoline filter housing to indicate the direction of gasoline flow. If you have a 1.5 engine, then the arrow should be directed to the port side, if 1.6, then to the starboard side.
Connection test
- We turn on the ignition for 6-7 seconds, then look at the fuel filter and look for a trace of smudges.
- If necessary, push the fuel line fittings onto the filter more tightly.
How much does a fuel filter cost
The estimated cost of an ordinary fuel filter is 100-400 rubles.
VAZ-2114 is one of the most massive and popular cars of the domestic auto giant. For 10 years of production, the car was equipped with four types of engines. They were of different design and power, consumed different amounts of fuel, but one thing united them - all units were injection. As you know, injection makes special demands on the quality of gasoline. And it directly depends on the fuel filter. A clogged element causes low pressure in the fuel system, resulting in loss of power. Its damage causes oil, water and dirt to enter the nozzles, and this is a direct road to a car service. To avoid this, you need to clearly understand when it is necessary to replace the VAZ 2114 fuel filter, and most importantly, know how to do it yourself.
It's time to change: when and how to change the fuel filter on the VAZ 2114
Like any malfunction, complete or partial clogging of the filter element has its own “symptoms”:
- Problems with starting the engine, which only get worse over time;
- The power unit does not work stably at idle;
- "Failure" during intensive acceleration;
- Loss of power under load;
- Significantly increased fuel consumption.
Of course, by one of the signs it is impossible to unequivocally establish a malfunction.
But if it is reliably known that since the last replacement the car has traveled about 20,000 km and refueled at different gas stations, the probability that the filter is to blame is high.
Moreover, even if there is no complete certainty, it is still better to change it before assuming a more complex malfunction.
Sometimes it is advised to measure the pressure in the fuel line. There is a reasonable grain in this, but this method is suitable only for experienced motorists who do not need advice. In addition, you will need a special pressure gauge, which, of course, is not in the arsenal of the average driver. Therefore, it will be easier and cheaper to change the fuel filter, and then, if this does not fix the problem, look for the problem further. Moreover, it is not at all difficult to do this on a VAZ 2114. But first you need to purchase a new filter.
Filter selection
The problem of buying a new fuel filter for the VAZ 2114 is not as far-fetched as it might seem. In any case, for those who will change it for the first time. The point is the difference in fuel filters on cars with a volume of 1.6 liters and on cars with one and a half liter engines. And they differ neither more nor less - in the way they are attached to the fuel line. In the first case, a spring mount is used, in the second, an obsolete threaded mount. Therefore, you need to decide which fuel filter to buy before going to the store.
In all other respects, it is no different from other fuel filters for the injector: it must withstand pressure up to 5 atmospheres and filter out foreign particles larger than 7 microns.
A few words about the price. You need to know in advance the average cost of a fuel filter on a VAZ 2114. The store will probably offer the most expensive copy. If its price differs greatly from the average, and this will be explained by better filtering, you should be skeptical about this.
The quality of domestic gasoline rarely allows you to drive more than 20,000 km on one filter, and this is much less than most manufacturers guarantee. Therefore, it is better to prefer a product of the middle price range and more frequent replacement.
Self-replacement of the fuel filter
If you contact a car service with this problem, the cost of work will rarely be lower than the cost of the part.

Meanwhile, changing the fuel filter on a VAZ 2114 is not difficult at all with your own hands. No special skills or tools are required. All you need is the desire and observance of TB.
Basic safety requirements
Works involving flammable and aggressive liquids are always associated with a certain risk. Therefore, it will not be superfluous to recall the safety rules:
- It is necessary to make it a rule that all work on the car associated with a possible fuel leak should be carried out with the negative terminal of the battery removed. This will prevent an accidental spark and save you from a fire;
- The room in which the repair will be carried out must be well ventilated;
- It is necessary to completely exclude sources of open fire, remove heating devices and, of course, forget about cigarettes and matches for a while;
- To prevent gasoline from getting into your eyes, you need to protect them with construction glasses.
And of course, do not forget the general requirements when working on pits and overpasses.
Preparatory work
Before proceeding with the replacement of the fuel filter, you need to finish with some little things. Namely:
- Agree on the account of a pit or overpass, if you don’t have your own;
- Prepare open-end wrenches for 10, 17 and 19;
- Stock up on a container for draining gasoline.
A fuel filter must be purchased and its completeness checked, in particular, the presence of new sealing rings.
Replacement procedure
First of all, the VAZ 2114 must be driven into the pit and be sure to put on the handbrake. Those who are replacing for the first time need to explain where the fuel filter is located on the VAZ 2114. It is located in the rear of the car under its trunk, next to the exhaust pipe. Immediately you need to pay attention to the direction of the arrow on the filter housing, this will come in handy when installing a new one. The further course of action is as follows:
- The pressure in the fuel system is relieved. There are several ways to do this, but the easiest is to remove fuse F. This will de-energize the fuel pump. Now just start the car and wait until it stalls. The ignition is turned off, the fuse is put in place;
- Remove the negative terminal from the battery;
- If the filter has a threaded connection, it must be treated with WD-40 or any equivalent;
- Holding the filter with a 19 key, with a 17 open-end wrench, you need to try to unscrew the fitting of the fuel supply hose from it. The main thing here is not to apply great efforts, otherwise the fitting breakage cannot be avoided.
- When the inlet fitting is unscrewed, a little gasoline will pour out of this part of the fuel line, you need to have time to substitute the prepared container;
- The outlet hose is unscrewed in the same way;
- Old sealing rings are removed from the fittings;
- Now you can remove the old filter using a key of 10. Care must be taken, because. the filter will also contain gasoline mixed with water.
- The filter is installed in the reverse order, but there is one caveat. It is necessary to exclude the ingress of gasoline on the sealing rings. If this happens, wipe them dry before installation. And of course, you need to remember about the direction of the arrow on the new filter.
- After the filter is in place and the fittings are tightly tightened, the connections are checked for gasoline leaks. To do this, the car must be started, but gasoline is first pumped into the highway. For this purpose, the ignition is turned on several times and, after the pump is running, the ignition is turned off. Only now can the engine be started and, taking precautions, the tightness of the tightening is checked.
- If everything is fine, replacing the fuel filter with a VAZ 2114 can be considered complete.
If the machine is equipped with a 1.6 liter engine, the sequence of work does not change, with the exception of the mount itself. In this case, simply release the latches, after which the filter can be removed.
