How Long Does a Fuel Pump Last?
1 Answers
Under normal circumstances, the lifespan of a fuel pump is about 5 years. The need to replace the fuel pump is mainly determined by mileage and fuel quality. If it does not affect engine performance, replacement is unnecessary. Reasons for fuel pump damage include: 1. Gasoline has a cooling and lubricating effect on the fuel pump. Failing to refuel promptly after the fuel warning light comes on can reduce the cooling and lubrication effects, leading to fuel pump damage. 2. Insufficient fuel pressure. When the fuel level warning light on the dashboard illuminates, there are approximately 7 liters of fuel remaining in the tank. Due to the low fuel level, the fuel pump motor does not receive adequate cooling and lubrication, which can cause overheating or even stalling. If the fuel pump frequently operates under these conditions, it may fail prematurely. 3. Long-term neglect of gasoline filter replacement. Severe clogging of the fuel supply system by the gasoline filter forces the fuel pump to work harder, and prolonged high-load operation can cause damage to the fuel pump. 4. Poor fuel quality. When the fuel tank contains various impurities or debris, the fuel pump draws fuel through its bottom filter screen and delivers it to the engine. During this process, large particles are filtered out, but small particles are sucked into the fuel pump motor, accelerating wear and causing early damage to the fuel pump.
