Delphi Fuel Injection Pressure Regulator P/N:FP10448
Delphi FP10075 fuel injection pressure regulator for the 1999-2005 Chevrolet Silverado 1500 V6 4.3L and other vehicles controls fuel pressure in the injection system.
Hard starting, a rough idle or poor fuel economy can mean the regulator no longer holds pressure. Those signs alone don't prove the regulator is the problem, since a clogged fuel filter is another common culprit.
The 1999-2005 GMC Sierra 1500 V6 4.3L and the 1996-1998 Chevrolet C1500 V6 4.3L fit this regulator too, along with many other Chevrolet, GMC and Oldsmobile models. Each engine takes one regulator, and this listing is one. If your vehicle isn't named here, look up its year, model and engine in the "Vehicles it fits" section.
