Last time the internal boost gauge stopped working on mine the vacuum pipe had come loose. In my case it was at the front of the engine bay, where the white vacuum pipe goes under the cold air inlet into the airbox but you'd have to trace it all the way around to find it including through the bulkhead and up under the dash.

I agree trace the vacuum pipe from the guage!
