Detailed Description
Delphi FG1664 is a fuel pump module assembly for diesel fuel delivery systems that require an in-tank electric pump and integrated sender. It is engineered for select Ram 3500 trucks and supports fuel system service where the original module has failed, the sender is inaccurate, or fuel delivery has become inconsistent. The module includes the float arm, seal, and instruction sheet, and uses an external strainer with a quick-connect outlet for straightforward fuel line connection.
Compatible With 2011-2021 Ram 3500, N/A. Compatible With 2022 Ram 3500, N/A. This part cross-references Spectra Premium SP7218M for the same application. Delphi FG1664 is also referenced by 6808 and 4721AA in interchange listings.
What It Helps Fix
- Hard starting caused by weak or failing diesel fuel delivery
- Fuel gauge readings that are inaccurate or intermittent
- Loss of fuel pressure in an in-tank pump module
- Contamination-related pump wear in aft axle tank applications
- Fuel starvation symptoms under load or during acceleration
Installation Notes and Tips
Before installing this Ram 3500 fuel pump module assembly, clean the fuel tank thoroughly if the vehicle uses an aft axle tank. Delphi recommends using a fuel tank cleaning kit such as FC01 to reduce contamination that can shorten pump life. Verify connector style, outlet configuration, and diesel fuel system requirements before installation.
Quality Assurance
Delphi draws on more than 100 years of OE experience and fuel system knowledge developed through work with leading automakers. FG1664 is built as a standard replacement part for select Ram 3500 diesel applications and follows OE-style design expectations for fit and function.
