Review on ACDelco Professional 217-3296 Fuel Injection Pressure Regulator: Fuel System Performance Maximizer by Shane Sanchez

Not the best option for plug and play on Camaro 3.8 engines. Those old Series II Buick fuel rails accept this, but the stock vacuum hose leaves too much room around the nipple, resulting in a leak if the hose system is not modified. The Delphi FP10016 is the right choice if you always want to keep your stock in order. Otherwise, this little fuel pressure regulator is a quality piece of equipment. And if you are replacing them on the F-Body, don't forget to replace the fuel injector o-rings and bushings as the fuel rail will need to be removed to replace the fuel pressure regulator. I use this. ACDelco 217-3102 GM OE Fuel Injector O-ring Kit with 8 grommets and 16 o-rings
