ACDelco GM OE Mechanical Fuel Pumps
ACDelco’s GM Original Equipment Mechanical Fuel Pump is a diaphragm positive displacement pump found on earlier-model carbureted engines. A rocker arm driven off the fuel pump camshaft lobe moves the diaphragm, causing fuel to be drawn in through a one-way inlet reed valve. As the cam lobe rotates away from the rocker arm, a spring pushes the diaphragm back, pushing the fuel out through a one-way outlet reed valve to the carburetor. This original equipment fuel pump has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

  • Able to fulfill original equipment specifications on earlier-model carbureted engines

  • GM-recommended replacement part for your GM vehicle’s original factory component
