Detailed Description

The Delphi FG0516 is an in-tank fuel pump module assembly engineered for gasoline fuel systems that require integrated pressure regulation and fuel level monitoring. It uses a 12.0-volt electric pump, blade terminals, and a quick-connect outlet layout to support service on select 2005-2006 Chevrolet Trailblazer and Trailblazer EXT, 2005-2006 GMC Envoy XL, 2005 GMC Envoy XUV, and 2005-2006 Isuzu Ascender models. Delphi’s OE background is reflected in the module’s design, which brings together the pump, sender, regulator, strainer, seal, and vapor pressure sensor in one service assembly.

This part cross-references Bosch 67508 and DENSO Auto Parts 953-3053 for the same application.

What It Helps Resolve

• Hard starting caused by weak or inconsistent fuel delivery
• Engine stalling from low fuel pressure in the tank module
• Incorrect fuel gauge readings from a worn sender assembly
• Fuel pressure regulation issues within the module
• Fuel system service needs tied to a damaged pump seal or strainer

Installation Notes and Tips

Before installing the Delphi FG0516, clean the fuel tank to help prevent future seal problems, as noted in the fitment data. Verify connector style, outlet configuration, and system pressure requirements before service. Because this is an in-tank module assembly, proper tank access and careful handling of the seal and sender components are important during replacement.

Quality Assurance

Delphi builds aftermarket fuel system parts using OE experience and knowledge developed through work with major automakers. The FG0516 is a standard replacement fuel pump module assembly intended to meet the needs of the listed Chevrolet, GMC, and Isuzu applications.
