First off does anyone else have a speedhut vacuum gauge? Maybe someone can shed some light on a problem im having before I call speedhut. My new vac gauge pegs at 30 and will not move. It won't even go back to zero and I have it hooked to the vac line above the pcv valve which has strong vacuum. I'm stumped and I know some of you run these gauges so maybe someone can help. Thanks!

These are nice gauges but I have to say I am NOT impressed. On top of this bad gauge they also sent me a cheap broken fuel pressure sending unit for my fuel gauge so now I have 2 out of 3 new gauges not working and these things cost enough.

The signal wire has 5v which is what I was told it should have from speedhut and I wired everything exactly as another member here did ( it was in the recent speedhit group purchase thread) but still no dice. I mean the wiring is so easy it baffles me as to what the problem is. Also my trans temp gauge is not reading either now. Once again it's just simple signal wire to the temp sensor and I don't understand the issue. My fuel pressure gauge is the only one working right now and it's wired the same way as the other two. I find it hard to believe that I got 2 bad gauges. Very discouraging to say the least. I wired the acc to the radio and the gauge lighting to the ashtray light and grounded everything. The vac gauge was zeroed when I got it and once I added power the needle made a full sweep. As soon as I hooked up the signal wire to the vacuum hose the needle jumped to 30 and now will not leave that spot.
