Detailed Description

Delphi MF0064 is engineered for classic Ford and Mercury fuel system service where a mechanical pump is required. The pump uses a hose-style inlet and outlet, a single outlet, and a 7 psi system pressure rating to support consistent fuel delivery in carbureted gasoline applications. Its 40 average flow rating and standard replacement design make it a direct service part for vehicles such as the Ford F-100, F-250, F-350, LTD, Thunderbird, and Mercury Colony Park.

This part cross-references Airtex Fuel Pumps 4008 and Carter M4008 for the same application. Delphi’s OE background is reflected in the application coverage and component design, which is built around long-running vehicle platforms and replacement service needs. Delphi MF0064 is also referenced by part number MF0064 for catalog and search use.

Common Repair Uses

• Restoring fuel delivery when the engine cranks but does not receive fuel
• Addressing hard-start conditions caused by a worn mechanical pump
• Correcting fuel starvation under load in carbureted systems
• Replacing a leaking pump or damaged fuel connections
• Servicing classic Ford and Mercury vehicles with integral-filter, two-line pump layouts

Installation Notes and Tips

Confirm the inlet outside diameter of 0.313 and the 1/2-20 UNF outlet fitting before installation. Verify that the vehicle uses a mechanical fuel pump with hose connections and the correct mounting pattern for the listed application. Clean the mounting surface, replace the gasket or seal during service, and follow the included instruction sheet for installation steps. MF0064 is a mechanical fuel pump for gasoline use only.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers. That OE heritage is applied to aftermarket replacement parts like MF0064 to support consistent fitment and service performance across the listed Ford and Mercury applications.
