The data show that the above 90% fault injector is due to fuel not clean caused. Therefore, the fuel filter plays a very important role in prolonging the service life of the components. The fuel system fuel filter, diesel filter, fuel filter and gas filter three. Its role is to remove the engine fuel system of harmful particles and water. The iron oxide containing in the fuel oil, dust and other solid debris removal, to protect the oil pump, cylinder liner, piston ring, prevent fuel clogging, especially nozzle. Reduce mechanical wear, to ensure stable operation of the engine, improve the reliability of operation.

The correct replacement steps of fuel filter  

In the assembly of the fuel filter, the filter must be installed at both ends of the sealing pad. If leakage around the sealing ring, the fuel filter inside the oil will be short, will lose the effect. The oil filter fuel filter replacement, unscrew old fuel filter together with the inside of the fuel will not scrap together, the old fuel filter fuel into new fuel in the filter, because the remaining old fuel filter fuel with a lot of impurities are filtered out of the cavity, clean into the new fuel filter after the fuel injection pump, fuel injector wear.
