Delphi FG2857 Fuel Pump Module Assembly

Fuel Pump Module Assembly Overview

The Delphi FG2857 fuel pump module assembly is a specific-fit, in-tank replacement built for gasoline applications. It combines the pump, sending unit, regulator, seal, and strainer in one assembly for a direct service solution.

Compatible With 2019-2025 Ram 1500, N/A. This Delphi fuel pump module assembly is engineered for 12-volt operation, a turbine-style pump design, and a quick-connect outlet for streamlined fuel delivery service.

Key Features

• Specific-fit fuel pump module assembly for gasoline applications
• In-tank electric pump with turbine design
• Fuel sending unit, regulator, seal, and strainer included
• Quick-connect outlet with oval female connector
• Plastic housing with nitrile rubber seal material
• Delphi FG2857 part number for accurate ordering and service matching

Detailed Product Information

Delphi FG2857 is built as a premium-grade fuel pump module assembly for vehicles that require an in-tank, electric fuel delivery unit. The assembly uses a turbine pump design, 12-volt electrical operation, and a 4-terminal blade connection with a single oval connector. It also includes a fuel sending unit and regulator, which helps consolidate key fuel system components into one service part.

For Ram 1500 fuel system service, this module is a direct replacement style solution that uses a quick-connect outlet and internal strainer arrangement. The FG2857 part number is also useful when cross-checking service references, and this part cross-references Mopar 6840 9161AB and 6840 9161AC for the same application.

Common Issues This Part Can Address

• Hard starting caused by weak fuel delivery
• Fuel pressure loss from a worn pump module
• Inaccurate fuel level readings from a failing sending unit
• Fuel starvation under load from restricted pump output
• Fuel system leaks related to a deteriorated seal or module connection

Installation Notes and Quality Assurance

Install this module in the fuel tank and verify connector, outlet, and seal compatibility before service. Confirm the vehicle uses the specified specific-fit configuration and follow the included instruction sheet during installation. The package contents list the fuel pump module assembly with float arm, seal, splices, wire harness, and instruction sheet.
