Fuel Pump Customer Reviews

Common Problems Fixed by the Fuel Pump

Based on customer reports and repair data, this part commonly fixes these issues:

About the Fuel Pump

The fuel pump has three ports: the gas in port, the gas out port, and the pulse port. The pulse port is connected to the engine crankcase by a small rubber tube. As the engine runs, air inside the crankcase alternately pressurizes and depressurizes the air in the tube. This pressurized air moves a diaphragm inside the pump and pumps the gas. If the engine oil is overfilled, oil can enter the pulse port line, preventing it from working properly. The fuel pump also has two small check valves on the input and output ports. The check valves prevent fuel from reentering the gas tank. These check valves can fail. To determine if the fuel pump is defective, check the pulse port line, check valves, and the diaphragm inside the pump. The fuel pump is not repairable—if the fuel pump is not working properly, you must replace it.
