When the fuel pump is broken, should we replace the pump core or the assembly?
Causes of broken fuel pump:
1. Insufficient Fuel in the tank When the fuel level warning light in the instrument is lit, there are about 7 liters of fuel left in the tank. Because the oil level is too low, the fuel pump motor is not sufficiently cooled and lubricated, which will cause the motor to overheat or even stop running. If the oil pump is often in this working state, then the premature damage of the oil pump is inevitable.
2, poor quality of oil because the quality of oil is poor, the fuel tank will be filled with various impurities or foreign bodies, fuel through the bottom of the filter suction fuel, pumped to the engine. In this process, the impurities of large particles are blocked by the filter screen, and the impurities of small particles are sucked into the oil pump motor, which is bound to aggravate the wear of the oil pump motor, resulting in the early damage of the oil pump.
3. The gasoline filter has not been replaced for a long time. The gasoline filter has not been replaced for a long time.
