I originally had the boost gauge connected in here to this bung circled in green. I just had the car tuned last weekend and I noticed the tuner disconnected the boost gauge line (red arrow) and reinstalled that tee fitting and left an open end with that short piece of vacuum hose to the left.If I join the open ended hose to the boost gauge hose will the gauge read correctly? All it needs is manifold pressure is that correct? Cheers guys Link to comment Share on other sites More sharing options...

Just put it back to the way you had it before tuning or whatever works now. As keefballs said, manifold pressure for the gauge and no leaks Link to comment Share on other sites More sharing options...
