Electric & Mechanical Fuel Pumps

Aftermarket electric fuel pump and mechanical fuel pump by Spectra Premium close-up product picture

Installed on top of the engine, the mechanical fuel pump is a lower-pressure pump that fits on older models from the 1950s to the 1980s. Its direct evolution, the electric fuel pump, is located within the fuel tank and delivers fuel through the fuel lines and fuel filter to the engine. Except for the Gasoline Direct Injection Pump, modern fuel pumps and fuel pump assemblies continue to be located in the tank and use the fuel in the fuel tank to prevent overheating.
