Installation Notes and Tips

Verify the vehicle uses a 3 line pump before ordering. Confirm the inlet and outlet style, including the hose bead inlet and threaded 5/8-18 UNF outlet, against the original pump before installation. Use the included gasket during service, and follow the instruction sheet for proper mounting and fuel line connection. The MF0011 is listed for specific Chevrolet and GMC applications, including several C/K series trucks and classic passenger models such as the Chevrolet Bel Air, Caprice, and Impala.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and knowledge developed through more than 100 years of original equipment experience. The MF0011 reflects that background with a standard replacement design for select Chevrolet and GMC fuel systems.
