Delphi Fuel Pump Module Assembly for Ram 3500 Diesel

The Delphi FG1664 fuel pump module assembly is designed specifically for diesel-powered Ram 3500 trucks. This in-tank electric fuel pump ensures reliable fuel delivery with precise flow and pressure control, supporting optimal engine performance.

  • Electric fuel pump module assembly with integrated fuel level sender
  • Compatible with 12.0-volt electrical systems
  • Designed for diesel fuel applications
  • Includes external strainer and gasket for secure installation
  • Quick connect outlet with 0.375 inch outside diameter
  • Four male blade terminals for secure electrical connections
  • Average flow rating of 80 liters per hour and system pressure of 20 psi

Technical Details and Features

The Delphi FG1664 fuel pump module assembly is engineered for the Ram 3500 diesel truck, providing a standard replacement solution. It operates at 12 volts and delivers a maximum pressure of 94 psi, ensuring consistent fuel supply under various driving conditions. The pump features an external strainer inlet and a quick connect outlet with three outlets, each measuring 0.375 inches in diameter. The assembly includes a fuel level sender with resistance values ranging from 50 ohms (full) to 990 ohms (empty), allowing accurate fuel gauge readings. The four male blade terminals facilitate reliable electrical connections, while the included gasket ensures a proper seal within the fuel tank. This module does not include a regulator or lock ring but comes with a strainer to protect the fuel system from contaminants.

Compatible Vehicles and Applications

This fuel pump module assembly is compatible with Ram 3500 diesel trucks requiring an in-tank electric fuel pump. It is suitable for replacing worn or failing fuel pumps that cause issues such as:

  • Intermittent or no fuel delivery to the engine
  • Erratic fuel gauge readings or inaccurate fuel level reporting
  • Reduced engine performance due to inconsistent fuel pressure
  • Fuel pump noise or electrical connection problems
  • Fuel contamination caused by damaged or missing strainers

Installation Notes and Tips

When installing the Delphi FG1664 fuel pump module assembly, ensure the vehicle’s battery is disconnected to prevent electrical hazards. Verify that the gasket is properly seated to avoid fuel leaks. The four male blade terminals should be connected securely to the corresponding wiring harness. Since this is an in-tank pump, handle the fuel tank carefully to prevent damage. Follow the included instruction sheet for detailed installation steps and torque specifications.

Quality Assurance and Warranty

Delphi provides a standard replacement grade fuel pump module assembly designed to meet OEM specifications for the Ram 3500 diesel truck. The product includes a fuel level sender assembly and strainer to maintain system integrity. While specific warranty details are not provided here, Delphi products typically come with manufacturer-backed warranties to ensure reliability and performance.
