Detailed Description

Delphi MF0108 is engineered as a mechanical fuel pump replacement for select rear-wheel-drive Ford, Mercury, and Lincoln applications that use a return-line fuel system or the listed two-line configuration on 1988 Mercury Grand Marquis. The pump’s threaded outlet design, hose bead inlet, and included gasket set support a straightforward service replacement for vehicles such as the Ford LTD, Mercury Grand Marquis, and Ford LTD Crown Victoria. This part cross-references Carter M60578 and FEL-PRO 60578 for the same application.

Delphi draws on more than a century of OE experience, and that background is reflected in the fit, form, and service focus of the MF0108. The part number MF0108 is a practical choice when replacing a worn mechanical fuel pump on compatible classic Ford and Mercury platforms.

What It Helps Address

  • Hard starting caused by weak fuel delivery
  • Fuel starvation under normal driving conditions
  • Low fuel pressure from a worn mechanical pump
  • Engine hesitation related to inconsistent fuel supply
  • Fuel system service needs on return-line equipped vehicles

Installation Notes and Tips

Verify the vehicle’s fuel system layout before installation, especially the 3-line pump and return-line configuration noted in the fitment data. Confirm the outlet thread size, inlet style, and system pressure requirements match the original setup before replacing the pump. Use the included gaskets during installation and follow the instruction sheet for proper mounting and fuel line connection. The MF0108 is listed for gasoline use only.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and application knowledge developed through long-term supplier experience with major automakers. The MF0108 is a standard replacement mechanical fuel pump backed by that OE-focused engineering approach.
