Re: Vaccuum Gage not working
I am suspecting the gauge. But I am not sure if i have enough vacuum. I am thinking about hooking it up to another vehicle with a situation that is working now, that way i can rule out the gauge itself.

Re: Vaccuum Gage not working
I feel kinda dumb...................I checked the obvious today, removed the gauge and looked in the opening behind the fitting on the back of gauge. I found a small screw valve in it. I turned it open 90* sucked on it holding it up to a mirror and it works fine!!!!!! I have no idea what the screw is. All I know is i love the fact this cool looking gauge is now working!!!! Timing and what not is off indicating low vacuum and all of the fittings to gauge are just finger tight as well. I was excited and wanted to take a picture so here it is!!!
