Installation Notes and Tips

Installation of the Delphi FD0040 requires an external in-line mounting position compatible with the vehicle’s fuel system layout. The pump includes a bracket, hose clamps, and mounting hardware to facilitate secure attachment. Ensure the female threaded inlet and outlet ports match the existing fuel lines with 0.500 inch outside diameter fittings. Proper electrical connections should be made using the lead wire terminals, verifying polarity and secure contacts. Since the pump does not include a gasket or wiring harness, these components must be sourced separately if needed.
