Can anyone with a Turbo or Supercharger help me out here? Where is the best place to get an accurate reading from? Is there somewhere simple to tap into or do I need to a drill hole and tap for a fitting? The intake manifold as everyone knows is plastic so I want to be carefull here, let me know guys.
Oh ya pics would be a great help.
Thanks.

 

I posted a reply on the thread I started. No need to repeat it. Did you plumb in a fuel pressure gauge?

 

on the right side of the manifold theres a connector that the A.I.R. trucks use for vacuum port. your truck should have it but its capped off. just break off the cap and tie it in there.

 

That's where I tapped in for my vacuum guage...just gotta snap that little cap off first.
