• ACDelco 40725 GM Original Equipment Mechanical Fuel Pump

An ACDelco GM Original Equipment Mechanical Fuel Pump is a diaphragm positive displacement pump. 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 specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.Stay with the parts brand your General Motors vehicle came with and get the quality you know and trust with ACDelco GM Original Equipment Fuel Pumps.
