I have a 1986 SPG and today the dash is out.
I heard a leak behind the dash, so today was the day to find it.

Can I bypass the over pressure switch or is it really needed?

I have one line of the intake and split it between the pressure transducer and the boost gauge. I don't run a ton of boost so I'm not worried about killing the engine.

I have about 12-14 inches vacuum at idle (shaky) and 18 at 1500 (solid).
More leaks or does this look about right?

And where does the #5 vac line on the distribution switch go? It was plugged, but the manual says its does the left side floor vent, but I can't find it. #6 I see where it goes. Maybe it was plugged from the factory?

Thanks - Carl
