Detailed Product Overview

This US Motor Works fuel pump module assembly, part number USEP3786M, is designed for direct replacement in the fuel tank on 2008-2011 Chevrolet Impala models. It combines the pump module and sending unit in one assembly to support consistent fuel delivery and accurate fuel level reporting. The module is built to OE-style specifications for the Impala fuel system and is suited for drivers replacing a worn or failing in-tank unit.

This part cross-references Delphi FG0939 for the same application.

Common Problems This Part Can Address

  • Hard starting caused by low fuel pressure
  • Engine stalling from inconsistent fuel delivery
  • Fuel gauge readings that do not match tank level
  • Loss of power under load from inadequate pump flow
  • No-start conditions related to a failed in-tank pump module

Installation Notes and Tips

Verify the vehicle is a 2008-2011 Chevrolet Impala before ordering. Because this is an in-tank assembly, access is typically through the fuel tank service area and the tank should be safely relieved of fuel pressure before removal. Confirm electrical connector condition, fuel line routing, and sender calibration during installation. Use the included installation instructions for proper setup.

Quality Assurance

US Motor Works states that its fuel modules are tested to meet or exceed original equipment specifications and manufactured with high-quality materials for consistent performance.
