Why Does the Fuel Pump Fail?
1 Answers
Fuel pump failure can occur due to the following reasons: 1. Low fuel level: When the fuel level in the tank is insufficient, the fuel warning light on the dashboard illuminates. This is because the fuel pump motor does not receive adequate cooling and lubrication, leading to overheating or even complete failure. Prolonged operation under such conditions accelerates fuel pump damage. 2. Poor fuel quality: Impurities or foreign particles in the gasoline can contaminate the fuel pump. If these particles enter the internal bearings of the pump, they accelerate bearing wear, resulting in pump failure. 3. Long-term neglect of fuel filter replacement: A clogged fuel filter forces the fuel pump to operate under high load for extended periods, ultimately causing damage to the pump.
