It is important to clean the Fuel Filter Media. The Fuel Filter Media string is on the line between the fuel pump and the throttle body inlet port.
The effect of the Fuel Filter Media is to remove the solid debris such as iron oxide and dust in the fuel, prevent the fuel system from clogging (especially the nozzle), reduce the mechanical wear, ensure the stable operation of the engine, improve the reliability, the fuel The structure is composed of an aluminum shell and a stainless steel bracket, the rack is equipped with high efficiency filter paper components, filter paper as chrysanthemum-shaped, to increase the flow area, EFI filter can not be with the carburetor filter Clearters are common. Because the EFI filter often withstand 200 ~ 300kPa fuel pressure. Therefore, the pressure resistance of the filter is generally required to reach more than 500kPa, carburetor filter can not meet the requirements.
The Fuel Filter Media must be replaced every 30,000 km. If the fuel impurity content is large, the travel distance should be reduced accordingly. The arrow on the Fuel Filter Media housing indicates the flow direction of the fuel, and no flush is allowed when the Fuel Filter Media is installed. Even if it is in the flip state to work for a short time must also be replaced.
Fuel Filter Media replacement cycle
Most of the car manufacturers to its external filter normal maintenance of the recommended replacement cycle of 48,000 km; conservative maintenance of the recommended replacement cycle is 1.92 ~ 24,000 km. If you are not sure, please read the owner manual to find the correct recommended replacement cycle. In addition, when the filter hose appears by the mud, oil and other dirt caused by aging or cracks, the need for timely replacement of the hose.
The recommended replacement cycle of the Fuel Filter Media should be different depending on its own structure, performance and use, and can not be generalized. If the filter is installed in the fuel line, it is called an external filter; otherwise, the internal filter is installed in the fuel pump and fuel tank inside the filter. Where the fuel tank filter or its protective cover is generally considered to be maintenance-free.
