Delphi MF0161 Mechanical Fuel Pump

Mechanical Fuel Pump for Ford and Mercury

The Delphi MF0161 is a standard replacement mechanical fuel pump for gasoline applications that require a 7 psi system pressure and a 30 average flow rating. Built from Delphi’s OE-focused heritage, it is a practical choice for restoring fuel delivery on select Ford and Mercury vehicles, including Mustang, LTD, Capri, Marquis, Fairmont, and Zephyr applications with a 2-line fuel pump.

Key Features

• Mechanical fuel pump for gas-powered engines
• 7 psi system pressure for OE-style fuel delivery
• 30 average flow rating
• Hose bead inlet with 0.313 inlet outside diameter
• Threaded outlet with 1/2-20 UNF fitting
• Standard replacement grade for direct service use
• Package contents include the mechanical fuel pump and instruction sheet

Detailed Description

Delphi MF0161 is engineered as a mechanical fuel pump replacement for vehicles that use a belt- or cam-driven fuel supply system rather than an electric pump. The threaded outlet, hose bead inlet, and 7 psi operating pressure support consistent fuel delivery for carbureted gasoline applications. Delphi’s OE background and broad aftermarket coverage are reflected in the design, making MF0161 a solid service part for restoring proper fuel flow on 1983-1986 Ford LTD, 1983-1986 Ford Mustang, 1983-1986 Mercury Capri, 1983-1986 Mercury Marquis, 1983 Ford Fairmont, and 1983 Mercury Zephyr models equipped with a 2-line fuel pump.

This part cross-references Carter M60048 for the same application.

What It Helps Fix

• Hard starting caused by weak fuel delivery
• Fuel starvation under load
• Low fuel pressure at the carburetor
• Engine stalling from inconsistent mechanical pumping
• Loss of drivability from an aging factory fuel pump

Installation Notes and Tips

• Verify the vehicle uses a 2-line fuel pump before ordering.
• Confirm inlet and outlet connection styles match the existing fuel lines.
• Inspect fuel lines, mounting surfaces, and pushrod or cam-driven components during replacement.
• Use the included instruction sheet for installation guidance.
• Because no gasket or seal is included, confirm whether the existing sealing components can be reused or replaced separately.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge developed with major automakers. That OE heritage is carried into this aftermarket mechanical fuel pump to support dependable service and application-specific fitment.
