Yeah, this is going to take some time.
One thing, that I would do before tearing the air system apart, is to disconnect the 120 compressor and dead head it into a gauge just to rule out a defective compressor before going any deeper. Quick, simple, and rules out one possibility.
Impossible to arm chair diagnose. One branch of logic you may want to pursue is the difference in air pressure behavior on the engine compressor vs the 120 compressor vs shop air input. The clues in that testing will help narrow the search.
Thanks for posting you are home safely, and thanks for posting what you find. It helps the next guy.
