Dirty diesel filter element will reduce the power of the engine, resulting in weak climbing and squeaking noise:
1. If the diesel filter element is not good, the debris in the diesel will easily block the small holes in the carburetor, making the carburetor work poorly, and the combustible mixture will become thinner;
2. The sundries in the diesel fuel enter the fuel injection pump, which is easy to accelerate the wear of the precision parts and reduce the pump oil pressure;
3. If the moisture and gum in the diesel enter the cylinder, it will cause the combustible mixture to burn badly and reduce the engine's power.

The most common locations for fuel filters are
1. In the fuel tank, at the junction of the fuel pipe on the chassis of the vehicle;
2. According to the fuel supply pipeline of the fuel injector, look upstream until the fuel tank. If it is external, you can definitely see it on the fuel supply pipe. If not, it is built into the fuel tank;
3. Fuel filter: There are three types of diesel filter, gasoline filter and natural gas filter. The function of the fuel filter is to prevent particles, water and impurities in the fuel, and to ensure that the precision parts of the fuel system are protected from wear and other damage;
