What is the design lifespan of a fuel pump?
1 Answers
The fuel pump does not have a definitive design lifespan. If no issues arise and it operates under normal driving conditions without affecting engine performance, a fuel pump can typically last around 100,000 kilometers, with some even lasting until the vehicle is scrapped. However, this also depends on fuel quality. Poor-quality gasoline can lead to deposits and wear inside the pump, reducing its pumping efficiency, which may necessitate cleaning or prompt replacement if damaged. Causes of fuel pump failure include: 1. Insufficient fuel in the tank: The fuel pump relies on the fuel passing through it for cooling. Inadequate cooling and lubrication can cause damage. 2. Long-term neglect of fuel filter maintenance: Severe clogging in the fuel supply system forces the pump to work harder, increasing wear and risk of failure under prolonged high load. 3. Poor fuel quality: Impurities in gasoline can enter the pump's internal bearings, accelerating wear and leading to failure.
