hey i know i have a 2.4 twin cam but since i got a charger i suppose this is the correct forum. I got a autometer phantom boost gauge that i just installed and for some reason the needle wont move on WOT at all, i had a regulator autometer gauge but i cracked the face taking it out somehow. heres some photos of my setup, white hose is the boost line from the gauge to the T fitting that goes to the fuel preasure regulator and the boost feed from the charger.

Everything has vac and when i spray compressed air through the whole setup the needle moves but once its hooked to the boost feed from the charger it wont and that has vac also coming from it. dont mind the dirty engine and the rusty s/c bolts
