So I bought my autometer vacuum/boost gauge today and its only reading vacuum. I connected it to the fuel pressure regulator line as I read on here... can anyone point me out to a line with prssure please!

 

Pull the cover off your intake.. There are nipples that you cut off, can purr a vacuum boot on it, along with a line..

 

Tell us more, i assume you have a blower?

I tubing from my blower manifold to a tee, The bullhead of the tee connects tubing to my fuel pressure reg. and the straight part of the tee is connected to tubing to my boost gauge.

Sounds like you dont have it hooked up to a boost reference?

 

Yeah I have the mp112 maggie
