What is a fuel filter? Fuel filter includes Diesel filter, gasoline Filter and Gas filter. Its role is to remove the solid debris contained in the fuel, prevent the fuel system blockage (especially the nozzle) reduce mechanical wear, to ensure the stable operation of the engine. In addition, the fuel filter also has the function of filtering water, in order to reduce the water in the fuel into the engine to produce fatal damage to the engine.
Fuel filter is divided into two kinds: one is external type, generally located in the lower chassis; The other is built in and sits in the tank. The two are just different installation location, the effect is the same. In addition, the external type is divided into ordinary direct into the direct type and with a return oil line of two. For different vehicles, the replacement cycle of the fuel filter is different. The specific need is to inquire the vehicle maintenance manual. If the fuel quality is not good, the replacement cycle can be shortened.
Problems that occur when fuel filters are not replaced regularly
The function of the fuel filter is to filter impurities in the fuel, but after a long time of use, the inside of the fuel filter may be blocked by impurities and affect the oil supply, resulting in reduced oil supply and difficulty in starting the engine. In addition, a prolonged blockage of the fuel filter can lead to premature damage to the gasoline pump.
The consequences of using a substandard, inferior fuel filter
The manufacturing material of inferior fuel filter is very poor, and the filtering effect is very poor. Long-term use of the internal filter element may lead to blockage of the oil circuit, resulting in insufficient fuel pressure and unable to start the vehicle. At the same time, it will also cause abnormal pressure of the fuel system, which directly leads to insufficient engine power or insufficient combustion, damaging valuable components such as three-way catalytic converters and oxygen sensors.
