You may need to run an 1/16" drill bit through there to get a good flow of air through it. Dedicate that port for ONLY the pressure regulation controller on the S/C. Get the vacuum supply for the gauge from another location that doesn't have a bellows attached to it. The fuel pressure regulator has a rubber flapper type bellows inside it and when it's working properly it will be fluttering when fuel demands change. This will cause funny readings on a vacuum gauge. I'm sure I'll be facing the same issue shortly since I have a vacuum gauge to install on my LS1 intake. I imagine I'll be drilling and tapping a hole some place for a 1/8" hose fitting to be JB welded into place.
