Delphi MF0098 Mechanical Fuel Pump

Mechanical Fuel Pump for Ford Heavy-Duty Applications

Delphi MF0098 is a standard replacement mechanical fuel pump for gas-powered Ford trucks and vans with GVW over 8,500 lb. It is built for 1985-1987 Ford E-250 Econoline, E-250 Econoline Club Wagon, E-350 Econoline, E-350 Econoline Club Wagon, F-250, and F-350 applications listed below.

With OE heritage behind the design, this pump is specified for direct-fit service on select Ford E-250 Econoline and F-350 models, helping restore proper fuel delivery in older mechanical fuel systems.

Key Features

• Mechanical fuel pump for gasoline applications
• Standard replacement grade for service repairs
• Average flow rating of 40
• System pressure rated at 5 psi
• Hose bead inlet with 0.375 in. outside diameter
• Threaded outlet with 1/2-20 UNF fitting thread size
• Two outlet ports
• Gasket included in the package contents

Detailed Description

Delphi MF0098 is a mechanical fuel pump engineered for select Ford heavy-duty platforms from 1985 through 1987. It uses a gas-fuel configuration, a hose bead inlet, and a threaded outlet arrangement to match the original-style fuel system layout on the listed vehicles. The pump’s 5 psi system pressure and 40 average flow rating support consistent fuel delivery for carbureted applications that rely on mechanical pumping action.

Delphi draws on more than a century of OE experience and supplier knowledge from top automakers, and that background is reflected in the aftermarket design of MF0098. This part cross-references Carter M60449 for the same application. Search terms such as 1986 Ford F-250 mechanical fuel pump, 1987 Ford E-350 Econoline fuel pump, and Delphi MF0098 fuel pump for Ford truck and van applications can help narrow the correct replacement.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Engine stalling from insufficient fuel pressure
• Fuel starvation under load in older mechanical systems
• Loss of prime or inconsistent pump output
• Driveability issues on carbureted Ford E-250 Econoline and F-350 models

Installation Notes and Tips

Verify the inlet and outlet style before installation, including the 0.375 in. inlet outside diameter and 1/2-20 UNF threaded outlet connection. Confirm vehicle GVW and build date for 1985 applications, since the listed fitment includes vehicles built from 12/1984 and only those with GVW over 8,500 lb. Use the included gasket during installation and inspect fuel lines, mounting surfaces, and the fuel system for wear or contamination before placing the vehicle back in service.

Quality Assurance
