Most of the Quads didn't have a pressure tap. If it does then get the adapter. If not I've drilled and tapped the fuel rail for 1/8 NPT then install any type valve. I'd like to give a big old thank you to GM for not providing a fuel pressure tap on alot of their engines since that's the first thing I check on a driveability issue. Joe
