Nowadays, high speeds and technology, the car has ceased to be a sign of luxury. Today, it is sometimes impossible to do without it, so it is important for each owner of the car that it is always in good working order.
What is a fuel filter
One of the most important elements of a car is a fuel filter. Its role is very significant in the car cleaning system. It is this detail that accounts for the main turnover of low-quality flammable mixtures. And before the fuel gets into the confined space, which is designed to burn fuel, this component provides relatively normal fuel filtration.
These elements are tape-slotted or plate-slotted. This component is necessary for any machine to clean the fuel from various impurities that impede its combustion. In order to make out where the fuel filter is located, you need a flyover or pit.
What is the fuel filter for?
In modern conditions, the quality of gasoline sometimes leaves much to be desired, and even prestigious stations are not immune to the purchase of low-quality fuel. It is he who helps to accelerate the wear of many parts. Therefore, the purpose of the filter becomes clear even from the name - filter the fuel from impurities. This part is optimally selected and installed in the system of each engine. Typically, gasoline can be diluted with water or various particles. And these impurities can get at the stage of production, storage or transportation, or due to contamination with oxides and dust inside the tank. It can also occur due to condensation that occurs when the temperature in the tank changes.
Depending on the fuel system of the machine, the place where the fuel filter is located also differs.
Carburetor system
Today, carburetor fuel systems are not used in the automotive industry. Nevertheless, our compatriots quite widely use models of past generations with such engines. Their cleaning scheme is simple and has one linear non-separable fuel filter.
Located in the carburetor system between the carburetor and the fuel tank, this element can sift particles of more than twenty microns. It has a transparent nylon casing, thanks to which it is possible to control the degree of contamination.
Injection system
Also, the fuel filter can be located in the injection system, the sensitivity to pollution of which is much higher than the previous one. Here, the filtration quality reaches five microns, and the body is made of a metal base and is located under the bottom of the car. Among other things, such an element can trap water.
The cleaning system of such machine models is multi-stage. The coarse cleaning function is performed by a special grid located on the fuel inlet of the tank. Its cells are very small, so the ability to clean this mesh in the event of clogging is virtually eliminated.
The next step is a fine filter, which, in fact, retains water.
In the event that a sufficient degree of filtration is not provided in the injection system, gasoline consumption will increase significantly, engine operation will become uneven, and start-up will become uncertain.
Propulsion system
Another fuel filter may be located at the highest point of the diesel system. Here, this element can trap air bubbles that often interfere with the fuel supply. Usually, where the Crafter's fuel filter is located, duplex filters are used that have a dual cleaning system that has an element that does not allow large particles to pass through and also has a size of less than two microns. Such a filtration system is called “fine cleaning”. Usually, it is present where the Nissan fuel filter is located.
Modern diesel engines are distinguished by their complex and accurate design, due to which the fuel is atomized more finely, due to which, in turn, the dosing becomes more accurate. In most cases, the filtration system in such filters is multi-stage and includes such elements as a fuel intake grid, a separator (filter sump), as well as coarse and fine filters.
In some systems, the presence of condensate in the fuel is automatically detected, above which the light on the dashboard begins to flash.
In order not to create conditions for the appearance of condensate and there was no room for air, experts recommend filling the fuel tank to the top.
Filter Change Frequency
There are often situations when the engine starts to troit when the driver adds gas. If you do not pay attention to this malfunction in time, then the motor soon begins to stall periodically. Only then does the car owner have to look for the cause of the breakdown.
Of course, there can be many of them, but most likely, the fuel filter became clogged. Most car manufacturers claim that the life of this part is equal to the life of the machine, but practice proves that this is wrong, and the filter must be replaced after every twenty thousandth run.
Today, quite a lot of people are trying to save on repairs, not contacting a car service, but independently replacing this part. But the complexity of this process depends entirely on the make and model of the car: replacing the filter in some cars seems to be a fairly easy procedure, and some require specialist intervention. Therefore, if you do not feel confident, do not do it yourself, it is better to entrust this procedure to professionals. In addition, they can show where the fuel filter is located.
It must be changed in case of severe contamination or the expiration date, despite the fact that domestic motorists have come up with ways to clean it. Replacement will be much safer, and the costs will be small.
Non-separable and collapsible fuel filters
Where is the fuel filter used in both the non-separable and the separable housing? Toyota usually contains this part in a monolithic, non-separable form. Such filters can be wound and direct-flow.
The former are usually used for fine cleaning or as pre-cleaners in multi-stage filtration systems.
The most common design for diesel engines is a non-separable straight-through filter, which has a water separator.
Today, such types of structures are used very little due to the fact that their disposal requires a large amount of financial costs. Fuel filters with replaceable elements are much more widespread. Modern plastics, from which such structures are made, are resistant to fuel.
Such filters of a new type are currently equipped with a large number of both cars and trucks.
Fuel filter arrangement
It is necessarily present in the power system of the internal combustion engine. Like any other part of the machine, the fuel filter has its own life, after which it must be replaced. But unfortunately, many people forget about this nuance due to the fact that this part has a rather long service life compared to other car filters. And the consequences of untimely filter replacement can occur after a fairly large amount of time. On average, a fuel filter must be replaced after forty thousand kilometers.
So still, where is the fuel filter in the car specifically? In modern car models, there are only two places in which it is located: in the engine compartment or under the bottom of the car (for example, the Matiz fuel filter - where the fuel line break is located, or in the fuel tank). Finding this part in various makes and models of cars differs insignificantly.
How to replace the fuel filter
Before you start repairing your car yourself, you need to purchase the necessary tools, as well as study the manual for your own car. Indeed, in some brands of machines, the filter is fixed on a special spring retainer, which cannot be removed with improvised means. As a result, without the availability of a special tool, independent replacement of the fuel filter in this case does not make sense.
Near the place where the Priora fuel filter is located, there is a valve through which it is necessary to relieve pressure. To do this, turn on the ignition and remove the fuel pump fuse from the fuse box . After this, it is necessary to start the engine, let it idle and stop on its own.
Next, you need to disconnect the quick-release latches and remove the filter. First you need to remember exactly the location of the old one and set it in such a way that the arrow drawn on the body indicates the direction of gasoline movement.
After that, in the place where the fuel filter is located (Kalina, for example, contains it near the rear wheel, not far from the fuel tank), you can install a new one. To do this, return all previously unscrewed fuses and parts to their places, and then start the car. This may not work right away, so don't be upset.
How to choose a fuel filter
Today in the automotive market there are a large number of manufacturers of this element, but where is a good quality fuel filter that can ideally suit your car, you can tell the sales assistant in your chosen salon.
One of the most common manufacturing companies are ACDelco, Motorcraft, as well as Fram. This part has a relatively low cost, but if you have a car on which the fuel filter is included in any system, then the entire assembly must be replaced.
