Detailed Description

Delphi MF0032 is engineered for diesel fuel delivery in older Dodge truck applications, including Dodge D250, Dodge D350, Dodge W250, and Dodge W350 models from 1989 through 1993. Built as a mechanical fuel pump, it uses threaded ports with 1/4-18 NPTF inlet and outlet fittings to match the specified fuel system connection style. The pump’s 6 psi system pressure and standard replacement design make it a practical choice for restoring consistent fuel supply in serviceable diesel setups. This part cross-references Airtex Fuel Pumps 1407 and Carter M73060 for the same application.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under load
• Inconsistent diesel fuel pressure
• Leaks at worn pump connections
• Service replacement for aging mechanical fuel pumps

Installation Notes and Tips

Confirm the vehicle’s fuel type, inlet and outlet thread size, and mounting configuration before installation. Use the included gasket during service, and follow the instruction sheet for proper pump orientation and connection tightening. Verify fuel system pressure after installation to confirm correct operation on the Dodge D250, Dodge D350, Dodge W250, or Dodge W350.

Quality Assurance

Delphi draws on more than a century of OE experience and a broad aftermarket portfolio built from original equipment knowledge. That background supports consistent part design and application coverage for diesel fuel system service.
