What to Do If the Fuel Pump Cover is Leaking?

[Gabriella]

The solution for a leaking fuel pump cover is: If the car is leaking engine oil, replace the sealing gasket; if it's leaking gasoline, the high-pressure fuel pump must be replaced. The reasons for a leaking fuel pump cover include: 1. The sealing gasket at the junction between the fuel pump and the crankcase is too thick; 2. The pump diaphragm is ruptured, or the seal between the diaphragm and the upper housing of the pump is not tight; 3. The inlet and outlet valves are stuck or have poor sealing; 4. Severe wear of the rocker arm reduces the diaphragm's stroke; 5. The pipeline from the fuel tank to the fuel pump is obstructed, or the diaphragm spring is faulty. The fuel pump is a component that draws gasoline from the fuel tank and delivers it through pipelines and the fuel filter to the float chamber of the carburetor. Based on the driving method, fuel pumps can be divided into two types: mechanically driven diaphragm type and electrically driven type.
