Re: Vaccuum Gage not working
It is the white plastic tubing that you see in the gauge kits. I can feel vaccuum if i unhook the fitting at the gauge and put my finger over it..... but it is a pulsation rather than a steady pull. I have had these lines come loose on other vehicles before and there is an annoying whistle... I unhooked the tubing at the manifold and don't hear a thing. I have a pretty heavy cam lift and duration. also.
