Fuel Filter P557440/Ff185 For Donaldson Brand

Product Description

The function of the fuel filter is to filter out harmful particles and water in the fuel gas system of the engine to protect the fuel pump nozzle, cylinder liner, piston ring, etc., reduce wear and avoid clogging.

Even though the diesel is cleaned by sedimentation and filtration before being added to the diesel fuel tank, the fuel will still be contaminated due to factors such as fueling tools, fueling environment, and unclean fuel tank ports during the fueling process. The impurities deposited in the fuel system and the suspended particles in the air will also pollute the diesel. Therefore, the diesel filter on the car is essential, not to mention that the diesel is not necessarily really clean before being added to the fuel tank.
