The fuel filter is an important part of the fuel system of each vehicle. This device is located between the fuel pump and the fuel tank. The first is responsible for supplying fuel to the engine, and the fuel filter delays the impurities existing in the fuel, which can cause nozzle clogging, and even car breakdown. In case of failure of this unit, the fuel filter is replaced.
Types of fuel filter
Before proceeding with the replacement of a failed fuel filter, you should determine its type. The fuel filter is flowing and submersible. The flow-through is connected to the fuel line. A submersible filter is a more complex design that is mounted in a gas tank.
Preparatory process
Since the procedure for replacing the fuel filter involves the emission of gases, as well as the pouring of a certain amount of fuel, therefore, this manipulation must be carried out in a room with good ventilation. It is better, of course, to replace this unit on the street. Safety glasses and nitrile disposable gloves should also be worn. In addition, you should not smoke when carrying out such work.
How to replace the fuel filter?
