Fuel Filter

Its function is to filter out harmful particles and moisture in the engine fuel gas system to protect the oil pump nozzle, cylinder liner, piston ring, etc., to reduce wear and avoid blockage. Filter out the iron oxide contained in the fuel.
Even if the diesel oil is precipitated and filtered before being added to the diesel fuel tank, it is clean. However, during the refueling process, the diesel fuel will be polluted due to factors such as the fueling tool, the fueling environment, and the fuel tank port are not clean, and during the operation of the diesel engine, Impurities deposited in the fuel system, suspended in the air, can also contaminate the diesel fuel, so the diesel filter on the car is essential, not to mention that the diesel fuel is not necessarily clean before it is added to the fuel tank.
