Where can I hook into to make a vacuum gauge work on my 04 silverado 4.8L?

Good question and I'm not 100% sure .. I have an 03 silverado myself .. I'll poke around with a few people I know and let ya know.

got it figured out. if you take the vortec cover off. in the middle of the intake manifold there is the pcv valve. will have a short rubber hose then turns into plastic tubing. runs along the driver side fuel rail. and goes in the head. i unhooked the tubing. cut a section out big enough for my t and some 3/8 rubber hose. simple as that.
