What to Do When the Car Fuel Pump Makes a Loud Humming Noise?
1 Answers
When the fuel pump makes a loud humming noise, it is mainly due to a problem with the fuel pump. It is recommended to replace the fuel pump. Here are the relevant details: 1. The function of the fuel pump is to draw gasoline from the fuel tank and pressurize it through the pipeline and fuel filter into the float chamber of the carburetor. It is precisely because of the fuel pump that the fuel tank can be placed at the rear of the car, far from the engine, and lower than the engine. 2. If it is confirmed that no other components are operating and the noise is indeed coming from the fuel pump, it indicates that the fuel pump has a temporary sticking phenomenon. The fuel pump relies on the gasoline itself for heat dissipation. If the fuel tank frequently has a low fuel level, it can cause damage to the fuel pump.
