Supercharger help needed, Hurry

The boost guage does not show boost, but does go from a vacume of -20 to almost zero

Boost gauge isn't hooked up right,I could tell you how to hook it up,but never installed one on my own car yet since I'm only currently runnin 6lbs of boost,no big deal at this point.

Do I still need a vacume line on the FPR

The vaccuum line needs to be attached though - that is how it raises the pressure based on boost. As your boost climbs,your fuel pressure raises also.
