Purpose of Fuel Filters?

[DeEmersyn]

Fuel filters primarily serve two purposes: 1. To remove solid impurities such as iron oxide and dust contained in the fuel, preventing clogging of the fuel system. 2. To reduce mechanical wear, ensure stable engine operation, and improve reliability. The fuel filter is installed in series on the pipeline between the fuel pump and the throttle body inlet. Its structure consists of an aluminum housing with a stainless steel bracket inside, on which high-efficiency filter paper is arranged in a chrysanthemum pattern to increase flow area. Fuel injection filters cannot be used interchangeably with carburetor filters. Since fuel injection filters frequently withstand fuel pressures of 200-300 KPA, their pressure resistance generally needs to exceed 500 KPA, whereas carburetor filters do not require such high pressure tolerance.
