Car fuel pumps should be replaced every 40,000 kilometers. The fuel pump is a crucial component of the electronic gasoline injection system in a car engine. The functions of the fuel pump are: 1. To provide hydraulic pressure for operating control valves and clutchers, and to supply a measured amount of gear oil to the transmission and differential case; 2. To deliver transmission oil to the cooler for circulation and heat dissipation. The maintenance methods for the fuel pump include: 1. Avoid using water-containing substances for vacuum extraction; 2. Use the fuel pump for vacuum extraction after removing most of the solvent in an oven; 3. Operate the vacuum pump in the correct sequence; 4. Add the specified grade of lubricating oil; 5. Ensure the fuel is clean, free from impurities and moisture.
