try not to tap into the fpr. if you're boosting your fuel pressure needs to be as accurate as possible. if that hose blows off or gets kinked you're in for some problems.

if i install someone's gauge i tap the vac hose for the emissions bs. this way you don't hurt any performance.

a quick writeup i did a little while back.

If you need help with the install, shoot me a PM.
