Detailed Description

Delphi MF0145 is engineered as a mechanical fuel pump replacement for classic Ford truck fuel systems that use a 2-line pump layout. It features a single outlet, 0.375-inch hose bead inlet and outlet connections, and gasoline-only operation with a 5 psi system pressure. This part cross-references Airtex 6618 for the same application. Delphi’s OE background and broad aftermarket coverage support consistent fitment for 1973-1976 Ford F-100, F-150, F-250, and F-350 models where the original mechanical pump is being serviced.

Common Uses

• Restoring fuel delivery on a worn or failing mechanical fuel pump
• Addressing hard-start or no-start conditions caused by low fuel pressure
• Correcting fuel starvation under load
• Replacing a leaking pump body or seal
• Servicing classic Ford truck fuel systems with a 2-line pump

Installation Notes and Tips

• Verify the vehicle uses a 2-line fuel pump before ordering.
• Confirm inlet and outlet hose size match the 0.375-inch bead connections.
• Use the included gaskets during installation.
• Inspect fuel lines and mounting surfaces for wear, corrosion, or contamination before installation.
• Prime and test the fuel system after installation to confirm proper pressure and flow.
