3. the replacement time
According to the manufacturer's recommendations: Different models of commercial vehicles and diesel filters have corresponding replacement cycles, which should be replaced in accordance with the manufacturer's recommendations.
Replacement according to the situation: If the filter effect of the diesel filter is found to be significantly reduced, or the fuel system is faulty, the filter should be checked and replaced immediately.
After long distance driving: Commercial vehicles after long distance driving, due to more impurities in the fuel, it is recommended to replace the diesel filter in advance.

4. Replacement steps
Preparation: Prepare new diesel filters, gaskets, tools, etc.
Fuel discharge: Turn off the engine, open the fuel discharge valve, and discharge the fuel in the filter.
