Assistance needed: X series boost gauge finding a vacuum source.
Running the 90mm Ktuned intake manifold, only comes with 3 NPT ports.. which are all currently used up. Brake booster gets the 5/8th center one, FPR gets one of the 1/8 NPT and the last NPT is for the BOV. My tuner said not to have the FPR Tee'd off anything and for my own reasons i won't T off the booster line. So, would T-ing off the BOV line be ok? i just got my manifold chrome plated so i'm not going to drill another hole and weld an NPT bung even tho i can. I have boost cut set up and BBG so this gauge is only to tell me if my solenoid has crapped the bed as there's a 6 psi difference from the spring to what the car sits at.and the v60 default spring. My last though was to just weld a bung for he sensor on the charge piping right before the TB.

Not practical just to see vaccum for 1 sensor, just need to see that its holding 22psi at 8000. Vaccum is not a must so if t-ing into the BOV line is sufficient great. If not I can't see why having the bung right by the throttle body wouldn't show boost.

Before the TB, you will always see positive pressure..

Decided to use one of Vibrant's "Y"s and have the lines split right at the manifold and use the push on ends hose size is 1/4". cab keep the tucked bay and still have a proper source.
