Car Fuel filter

Fuel filter is necessary for all cars without any exceptions and not depending on the kind of fuel used - petrol or diesel fuel. Fuel that is sold on fuel station is already filtered, but still particles of solid substance can get into it. Small particles that come off the inside part of the fuel holding tank or petrol pump can easily provoke dirtying of the air filter. The dust that gets into the tank must be filtered before fuel supply to the engine.

Fuel filter is responsible for the supplying of clean fuel into the engine. This ensures efficiency and prolongs service life. In many cases fuel filter for carburetor engine is situated in the inlet manifold, but for diesel engine filter in form of a cartridge is fixed with flange. It is necessary regularly to change the fuel filter, because it blocks with solid particles of fuel. In this case you need to examine it. If the engine doesn’t work on full power the reason also may be in the blocked filter. After the filter is changed the engine again works with optimal power.

To install a new filter in your car isn’t a difficult task. Every car owner can do this without any problem. Of course, it is necessary to take into consideration that before you install the fuel filter inside it must be fuel. This will make engine start easy because without enough fuel supply of fuel to the petrol pipe may be interrupted.

Fuel filter failures

• fuel filter is soiled;
• the part has mechanical damages;
• seal and gaskets are damaged.

Signs of failures

• the engine speeds up slowly;
• fuel consumption increases;
• the ultimate engine output decreases;
• the engine works erratically at all modes;
• start-up of the engine is difficult;
• ignition is absent;
• gears switch incorrectly (relevant to automatic gearbox).

Causes of failures

• fuel of poor quality is used;
• the engine often idles;
• tiny foreign particles get into the fuel tank;
• the filter is installed incorrectly;
• rubber sealer of the filter is detached.

Diagnostics

The filter should be checked regularly, every 10 000 operational kilometers preferably. Manufacturers of fuel system components generally regulate the term of their service in 50 000 - 60 000 operational kilometers, but it is better to change filters twice more often for ensuring proper work of all the system.

Repair and replacement

It is very convenient to entrust the replacement of the fuel filter to specialists, though this procedure is quite easy.

Consider the following recommendations during replacement:

• it is preferable to carry out all works in the warm room;
• consider fragility of fuel system parts;
• take into consideration the fuel filter location: in petrol cars it is situated in the tank, next to the gasoline pump, in diesel engines — under the bonnet, at the upper engine side.
• do not forget about the accident prevention: refrain from smoking and air the room well.
