Stable and efficient engine operation on Lada Granta cars is ensured by spark plugs, air and fuel filters. Manufacturing companies establish a certain frequency for changing filter elements: under normal operating conditions, they are changed every 25–30 thousand kilometers traveled. Many experts advise changing fuel system filters one and a half to two times more often than specified by the manufacturer to maintain the performance of the power unit.

We start the engine and let it idle until it stops due to fuel exhaustion. Then turn on the starter for 3-4 seconds. After this, the pressure in the fuel system will be released.
The fuel filter is mounted on the fuel tank next to the right side sill.
Causes of fuel filter failure
The fuel at our gas stations is not cleaned as it should be - it may contain dust particles or other contaminants. All this debris ends up in the fuel filter, which does not allow it to pass further into the system. But over time, as pollution accumulates in it, it ceases to cope with its responsibilities. This is very dangerous because it can cause damage not only to many components of the fuel system, but also to the power plant.
If you delay the change, problems may arise with the injectors, valves, and ultimately the engine will refuse to work at all. That is why it is important to know the symptoms of fuel barrier contamination, and if detected, replace this part in a timely manner.

We put the tips of the fuel pipes onto the filter fittings until the clamps snap into place.
Why is it needed?
There is a coarse filter that comes first from the gas tank. After all, first the lid where the fuel tank is located is opened, a gun is inserted there, the magic button is pressed and the fuel flows. Yes, it takes a lot of your money along the way, but what can you do? The location of the tank can be on the left or right, but this does not play a special role. Coarse cleaning, which is a mesh that traps large particles of debris.
This is followed by a fine filter. This is exactly what we will talk about. This element is called a fuel filter. With its help, small particles are retained. But even they can penetrate your diesel engine or gasoline injector.
Dust, dirt, debris, rust elements. All this can penetrate the system, causing a clogged pipe, tube, valve, fuel hose, or fuel pump components. Nothing good will come of this if timely replacement is not made.
To understand how to replace the filter, which element to choose and how to choose an analogue for the device you are going to change, you need to have at least a basic understanding of such an important component of the car.
I suggest starting with varieties.
Modern fuel filters installed on Ford Focus, Nissan Almera, Hyundai Solaris, Nexia, Mazda, Opel, BMW e60, Renault Logan and Megane, Kia Rio and many others have at least two degrees of purification.
- First degree. This is a rough cleansing that allows you to get rid of large contaminants. Not to be confused with a regular mesh in the tank, which is not available everywhere.
- Second degree. Fine cleaning. This is the main task that falls on the shoulders of the filter.
And here you probably have the main question - where is the filter device located? I don't know. No, I can answer, but if you tell me specifically what make of your car or what year of manufacture. After all, on the same Chevrolet Niva, different Opel, Toyota, Mazda models, on the Volkswagen Passat B3, as well as on the domestic VAZ 2114, 2112 and 2110, the location may differ.
However, they are always located somewhere between the engine and the gas tank, since the filter's job is to prevent contaminants from entering the engine while the fuel moves from the tank to the engine. What's in the gas tank itself? That's right, a coarse cleaning device. This is an additional filter element so that any unscrupulous gas stations do not spoil your car.
Now let’s talk about the types of filters themselves. What element will be on the car? It depends on the type of engine. There are three of them, as you know. Except for electric motors. Well, there is no need for a fuel filter, as you understand.
Therefore, there are three types of filters:
Location
So you bought yourself a brand new sedan and you think it’s time to change the filter for this engine. Want to choose the best? Well then, take a closer look at Cummins devices. Mann, Hertz. They have proven themselves well, and they cost quite a bit.
You probably know whether your engine is diesel, injection or carburetor
This is important to understand the location of the fine filter, that is, our today's hero
- Carburetor. In these engines, the TF (fuel filter) is placed in front of the carburetor itself, and is often in a transparent housing to control contamination. These are the most basic devices, because the carburetor is the least demanding on the quality of fuel.
- Injector. It uses nozzles and therefore requires high-quality filtration. And the fuel is supplied under high pressure. Therefore, the filters are enclosed in durable metal housings. The TF has to be regularly maintained, cleaned and monitored for its condition. They are placed mainly under the bottom of the car to make it easier to dismantle and replace.
- Diesel. A diesel engine also needs high-quality purified fuel, since the system is quite sensitive. Diesel fuel has a higher moisture content than gasoline. The TF is designed to filter debris and remove accumulated moisture. A separator is provided for this purpose. The location is quite simple - between the engine and the pump that pumps fuel.
Any fuel system must include a TF. They are replaced assembled, that is, there is no point in removing the filter elements themselves (usually special paper), leaving plastic or metal. Be sure to look at the number and article number of the filter that is installed on your machine, and check the operating manual from the factory. This is the only source of truthful information regarding the maintenance of your particular vehicle in this configuration and with this type of engine.

Replacing the Lada Granta fuel filter
Every 10,000 km (or once a year)
Mileage is not the only indicator that it is time to take action. If you haven’t made ten in one year, then it’s time to use the memo in the same way. Simply put, you should service your car once a year or every 10,000 km. We list all the necessary maintenance procedures corresponding to a given mileage (time):
The most important procedure is changing the oil. If it is not changed in a timely manner, there is a high probability of a significant reduction in the service life of your car’s internal combustion engine. If the car is “aged”, then it is advisable to use flushing oil. It is necessary to change the oil filter along with the oil, otherwise the replacement procedure will be useless
Buy filters only from trusted manufacturers

The air filter also needs to be changed promptly. If you do not replace it in a timely manner, then, at best, the power of the car will noticeably decrease. In the worst case, the filter may rupture, which will lead to wear on the working surfaces of the cylinders and valve seats - and this is already halfway to an expensive overhaul.
Cabin filter - untimely replacement is unlikely to have any effect on the performance of other components of the car, but your lungs probably won’t like it, especially if you live in a dirty city or often drive along dusty roads.
Suspension diagnostics
Don't expect an unpleasant knock while driving - after all, the chassis is an important component of your safety. In addition, a consequence of a worn-out chassis may be a violation of the wheel alignment angles, which will undoubtedly lead to tire wear
Diagnostics of the brake system. Another important element of security is that you probably don’t need to explain to anyone that this system simply needs to be maintained in working order. Check the brake fluid level and any leaks all the way from the reservoir to the brake calipers.
Diagnostics of lighting devices. As a rule, low and high beam headlights make themselves known immediately. The turn signal relay also indicates a malfunction when it accelerates the blinking frequency (this is due to a decrease in resistance). But as for the side lights, brake lights, as well as reversing lights, you may simply not notice their malfunction. In order to diagnose the latter without outside help, it is enough to park the car near the wall in the dark and check the functionality of the light bulbs in the reflection.
Checking the coolant level. Modern cars are equipped with systems that can warn you about an antifreeze leak, but this does not guarantee that it will not be too late. A lack of even a small amount of coolant can lead to overheating of individual engine elements, which will lead to very unpleasant consequences.
The most expensive of all the above will be changing the oil. Filters, as a rule, are not expensive and replacing them is not difficult. To be sure, the last 4 points can be done more often, since self-diagnosis does not require financial costs and can increase the likelihood of timely detection of faults.
