• In-tank electric fuel pump module assembly for flex-fuel systems
• Includes fuel level sender assembly, regulator, strainer, gasket, and seal
• Quick-connect outlet design with 2 outlets and 4 blade terminals
• Operates at 13.0 volts with an average current draw of 11 amps

Detailed Description

Delphi FG0815 is engineered for in-tank fuel delivery on select GM trucks and SUVs, including 2005-2007 Chevrolet Suburban 1500, 2005-2006 Chevrolet Avalanche 1500, and 2007 Chevrolet Avalanche, plus 2005-2007 GMC Yukon XL 1500. It is built for flex-fuel service and includes the fuel level sender assembly, helping restore both fuel delivery and tank level reporting in one repair.

This fuel pump module assembly uses a quick-connect outlet, internal strainer, and male blade terminals for a straightforward OE-style replacement. Delphi draws on more than 100 years of OE experience and supplier knowledge used by major automakers, and that background is reflected in the FG0815 design and application coverage. This part cross-references Bosch 66031 and Airtex E3706M for the same application.

What It Helps Fix

• Hard starting caused by weak or failing fuel pressure
• Engine stalling from inconsistent in-tank fuel delivery
• Fuel gauge errors related to a worn sender assembly
• Low fuel pressure under load in flex-fuel GM applications
• Noise or performance issues from an aging pump module

Installation Notes and Tips

Before installation, clean the fuel tank to prevent future seal problems, as noted for the listed applications. Verify connector style, outlet configuration, and system pressure requirements before service. Because this is an in-tank module assembly, proper sealing at the tank opening is important for reliable operation.

Quality Assurance

Delphi builds this FG0815 module using OE-based engineering knowledge and a broad aftermarket portfolio developed from long-term supplier experience with major automakers. The part is supplied as a standard replacement fuel pump module assembly for the listed Chevrolet and GMC applications.
