The function of the Fuel Filter

The function of the Fuel Filter is to filter out harmful particles and water from the engine fuel gas system in order to protect the fuel pump nozzles, cylinder liners, piston rings, etc., reduce wear and prevent blockages. The function of the Fuel Filter is to remove solid debris such as iron oxide and dust from the fuel to prevent clogging of the fuel system (especially the injector nozzles). This reduces mechanical wear and tear, ensures stable engine operation, and increases reliability.

Working principle of the Fuel Filter

The fuel filter is connected in series to the line between the fuel pump and the throttle body inlet. The function of the fuel filter is to remove solid debris such as iron oxide and dust from the fuel and to prevent blockages in the fuel system (especially in the injectors). It reduces mechanical wear and tear, ensures stable engine operation, and increases reliability. The structure of the fuel filter consists of an aluminum housing and a stainless steel bracket with a high-efficiency paper filter in a daisy shape to increase the circulation area.
