Review on ⛽️ ACDelco GM Original Equipment 217-1445 Fuel Injection Pressure Regulator: Enhanced Performance and Reliability by Mike Burnett

Installed on a 2004 Trailblazer with an inline 6 cylinder engine. Installation was easy as the part came with the required o-rings. I just added a small amount of engine oil from the dipstick to lubricate them so they snapped into place. This is an OEM part and the bracket and fitment are the same as the original. FWIW I had an issue with fuel getting into the airbox and smelled like fuel after the truck was parked. Fuel seeped through the membrane and entered the tube connected to the air chamber.
