The gauge is teed off the hose going between the intake manifold and BPV. I don't think you can use that for diagnosis though, if there is a leak and pressure drop, the pressure is lower everywhere in the loop. You said the gauge goes almost to the end of the yellow, so it is reading differently than before. The intercooler can definitely develop a leak, the ends are plastic and crimped onto the core with aluminium "fingers". To test the intercooler you need to pressurise the system, which requires blocking off one end and applying pressure at the other end while maintaining a seal. I used an end cap for PVC drain pipe on both ends, with a 1/4" NPT fitting insterted into one of them to attach the pressure hose.
