Detailed Description

Delphi FG1978 is a fuel pump module assembly for diesel Ram trucks that require an in-tank replacement with integrated fuel level sending capability. It is built as a standard replacement part and includes the pump module, float arm, seal, and instruction sheet. The module uses an internal strainer, quick-connect outlets, and a 0.375 outlet outside diameter for service-friendly fuel line connection.

This part cross-references Spectra Premium SP7251M for the same application. The Delphi FG1978 is a direct-fit service option for Ram 1500 and Ram 1500 Classic diesel fuel delivery repair work where the original module has failed, the sender is inaccurate, or fuel pressure has dropped below specification.

What It Helps Fix

• Hard starting caused by weak fuel delivery
• Engine stalling from inconsistent pump output
• Incorrect fuel gauge readings from a worn sender
• Low fuel pressure in diesel Ram applications
• Fuel starvation from a clogged or failing in-tank module

Installation Notes and Tips

Before installation, clean the fuel tank to prevent future seal problems, as noted for the listed Ram applications. Verify the vehicle uses the correct diesel in-tank configuration and confirm connector, outlet, and terminal style before service. Replace the module only after the tank is safely drained and the system is depressurized.

Quality Assurance

Delphi builds this replacement module using OE heritage and application knowledge developed through long-term supplier experience with major automakers. The FG1978 is designed to meet the needs of diesel fuel delivery service on Ram 1500 and Ram 1500 Classic models.
