Boost gauge

[whudafux]

I hooked up my boost gauge but it's not reading any boost. I hooked it up to the vac line coming from the back of the manifold going to the cruise control unit. It looked like it was hooked up there in most of the threads I looked at. Any help?

PS - And yes it is hooked up to the back of the gauge, lol.

What brand of guage is it? Most guages you can google installation instructions.

Are you sure the power and ground are hooked up?

Is it reading anything? (vacuum)

It's a Stewart Warner boost gauge. It's mechanical so the only thing to hook up is the light, and it's only a boost not boost/vacuum and it stays at 0. I guess I should've mentioned that the car is not moving when I'm looking at it. I'm only revving it. Not sure if it matters tho. I just thought I would add that.

Hose kinked or pinched running through the firewall?

Not sure, it shouldnt be, it has enough room, but i'll check on it tomorrow.

It's a mechanical gauge, so there's only so many things that would cause the gauge to not read. Hose not attached at one or both ends > proper vac source > kinked/pinched hose > faulty gauge.

Well, if it's a faulty gauge someone has some explaining to do. Lol. But I don't think it is. I blew into it and the needle went up. Is that a good place to draw vacuum for the gauge from? And I'll check on the hose to see if it's pinched or disconnected.

If you're just reving it... you're most likely not seeing boost.

You're going to have to drive it.

if you have a brand new t fitting you should be fine. double check on the pinched hose. the previous owner of mine hooked it up by cutting a vacuum line and then used scotch tape to secure it. and then when he sold me the car he was wondering why it woulnt read anything.:3d_frown:

That's a good point. I missed that post.

Drive it and get back to us.

Go drive it then see if it moves or not.
