Delphi FG1943 Fuel Pump Module Assembly
The Delphi FG1943 fuel pump module assembly is a standard replacement for diesel Ram heavy-duty applications. Built with OE heritage and backed by Delphi’s long history supplying automakers, it combines the pump, fuel level sender, regulator, and internal strainer in one in-tank module.
Compatible with 2011-2024 Ram 2500 and Ram 3500 applications, this module is built for diesel fuel systems that require stable pressure and reliable fuel delivery. The FG1943 is a direct-fit service part for Ram 2500 and Ram 3500 trucks where the original in-tank module has worn, lost pressure, or developed sender issues.
Key Features
- Delphi FG1943 fuel pump module assembly for diesel applications
- In-tank electric pump design with quick-connect outlet
- Fuel pressure regulator included
- Fuel level sender assembly included
- Internal strainer and inlet strainer included
- Standard replacement grade for service repair
- 13.5-volt operation with 13 psi system pressure
- Average flow rating of 45 and average current draw of 6
- Blade terminal design with 4 terminals and male terminal gender
Detailed Description
The Delphi FG1943 is engineered as an in-tank fuel pump module assembly for diesel fuel delivery systems. It features a quick-connect outlet, two outlet ports, a built-in regulator, and an integrated fuel level sender assembly to restore both fuel supply and tank level reporting in one service part. The module also includes a strainer and internal strainer to help support cleaner fuel delivery through the system.
Delphi draws on OE experience and supplier knowledge built over decades of original-equipment development, and that background is reflected in the FG1943’s service-focused design. This part cross-references Airtex E7277M and Carter P77037M for the same application. Search terms such as Delphi FG1943 fuel pump module assembly for Ram 2500 diesel and Ram 3500 in-tank fuel pump replacement align with this part’s intended vehicle coverage.
What It Helps Address
- Hard starting caused by weak diesel fuel delivery
- Low fuel pressure from a worn in-tank pump module
- Inaccurate fuel level readings from a failing sender
- Fuel starvation under load or during acceleration
- Driveability issues related to inconsistent pump output
Installation Notes and Tips
- Fits 2022-2024 Ram 2500, N/A
- Fits 2022-2024 Ram 3500, N/A
- Fits 2011-2021 Ram 2500, N/A; clean fuel tank before installing fuel pump to prevent future seal problems.
- Fits 2011-2021 Ram 3500, N/A; clean fuel tank before installing fuel pump to prevent future seal problems.
