Technical Details and Features

The Delphi FG1943 fuel pump module assembly operates at 13.5 volts and is engineered for diesel fuel systems. It features an internal strainer inlet type and a quick connect outlet with two outlets measuring 0.375 inches in diameter. The module includes a regulator to maintain fuel pressure up to 15 psi, ensuring steady fuel delivery to the engine. The assembly comes with a fuel level sender assembly, including a float arm, allowing accurate fuel level readings. Electrical connections are made via four male blade terminals, providing a secure and reliable interface. The pump’s resistance ranges from 50 ohms when full to 990 ohms when empty, with an average current draw of 6 amps and a flow rating of 45, suitable for heavy-duty diesel applications.

Compatible Vehicles and Applications

This fuel pump module assembly is compatible with Ram 2500 and Ram 3500 diesel trucks. It is designed as a standard replacement part for in-tank fuel delivery systems, making it suitable for restoring proper fuel pressure and flow in these specific models.

• Resolves fuel delivery issues such as low fuel pressure or inconsistent flow
• Replaces faulty or worn-out fuel pump modules in Ram 2500 and 3500 diesel trucks
• Addresses inaccurate fuel level readings due to faulty sender assemblies
• Helps eliminate engine performance problems caused by fuel starvation
• Prevents stalling or hesitation related to fuel pump failure

Installation Notes and Tips

Installation of the Delphi FG1943 fuel pump module assembly requires removal of the fuel tank to access the in-tank pump. Ensure the electrical connections match the four male blade terminals and verify the quick connect outlet fittings are secure. The assembly does not include a gasket or lock ring, so reuse or replacement of these components may be necessary depending on the vehicle’s condition. Follow all safety precautions when working with diesel fuel systems and consult the vehicle’s service manual for detailed installation instructions.
