Detailed Description

Delphi FG1511 is an in-tank fuel pump module assembly engineered for select Chevrolet Impala and Chevrolet Impala Limited models. It is built as a complete fuel delivery module with the pump, internal strainer, fuel level sender assembly, regulator, seal, and float arm, helping restore proper fuel supply and tank level reporting in one service part. The module uses a quick-connect outlet, blade terminals, and a male terminal configuration for straightforward integration with the vehicle’s fuel system layout.

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers, and that background is reflected in the design and application coverage of the FG1511. This part cross-references Delphi DFG1511 and Spectra Premium SP6659M for the same application. Compatible with 2012-2013 Chevrolet Impala and 2014-2016 Chevrolet Impala Limited, this fuel pump module assembly is a direct service option for vehicles requiring a flex-fuel in-tank module.

What It Helps Fix

• Hard starting caused by weak or inconsistent fuel delivery
• Fuel pressure loss that affects acceleration or engine performance
• Inaccurate fuel gauge readings from a failing sender
• Fuel pump noise or intermittent pump operation
• Driveability issues related to a worn in-tank fuel module

Installation Notes and Tips

Before installation, clean the fuel tank thoroughly to reduce the risk of contamination entering the new pump module. For the listed Chevrolet Impala applications, follow the manufacturer note regarding the two-port cover: do not tamper with the plugged port, and use the open port to help prevent contamination that can lead to premature pump failure. Delphi includes an instruction sheet with the package contents, and the module uses a gasket or seal for installation.

Quality Assurance

Delphi builds this fuel pump module assembly using OE-based engineering knowledge developed through long-term supplier experience with major automakers. The FG1511 is a standard replacement part designed to meet the fuel system requirements of the listed Chevrolet Impala applications.
