Delphi Fuel Pump Module Assembly P/N:FG0271
Delphi FG0516 fuel pump module for the 2005-2006 Chevrolet Trailblazer EXT 6-cylinder 4.2L or V8 5.3L and other vehicles holds the pump and float arm that move fuel from the tank to the engine. The Delphi fuel pump module assembly is built to Delphi's OE standards.
Hard starting, stalling or sputtering under load can mean the fuel pump assembly is wearing out. Those signs have other causes too, so with the engine off, look at the fuel pump fuse first. If the module is the cause, this one replaces it.
As a direct-fit replacement, this fuel pump module also suits the 2005-2006 GMC Envoy XL 6-cylinder 4.2L or V8 5.3L and the 2005-2006 Isuzu Ascender 6-cylinder 4.2L or V8 5.3L. One module goes in each vehicle. Don't see yours? The "Vehicles it fits" section is where to look up your own vehicle.
