Can someone show me where a good vacuum line is that I can 'T' into for a boost gauge. For some reason I can't find it in the Hayne's manual, and I would rather not guess. This question probably outs me as a beginner, but hey, we all got to start somewhere.

I appreciate the help.

Yeah sure man, here is where I tapped my boost gauge in:

Very much appreciated!

Just out of curiosity, how much vacuum should your boost gauge read when its hooked up?

about 20 vac at idle

Thats what I think mine used to read. When I put my boost gauge in I kinked the vaccum line and tried to straighten it back out but now at idle it only reads about 10 vaccum. I think the vaccum hose collaped back on itself making it not read right. Thanks for your quick reply by the way.

Yeah mine reads about 20-25 vac at idle.

mine was reading 15 one time, it was becuase another vac line had become disconnected.

Out of curiosity is there a set of good reasons to have a boost reading below zero? (mine doesn't go that low)

If your using a map sensor it will only go to about -10, only reason to look at the true vac reading would be to see if you had a vac leak is all I could think of.
