What Causes Abnormal Noise in the Fuel Pump?

[LeJayla]

The causes of abnormal noise in the fuel pump are: 1. Insufficient fuel in the tank: When the fuel level is too low, the fuel pump motor does not receive adequate cooling and lubrication, leading to overheating or even stalling. Frequent operation under such conditions will inevitably result in premature damage to the fuel pump. 2. Poor fuel quality: When the fuel quality is poor, the fuel tank may contain various impurities or foreign objects. The fuel pump draws fuel through the filter screen at its bottom and delivers it to the engine. The fuel pump is a component that draws gasoline from the fuel tank and delivers it through the pipeline and fuel filter to the carburetor's float chamber. Based on the driving method, fuel pumps can be divided into two types: mechanically driven diaphragm type and electrically driven type.
