Ok, you obviously have a massive leak somewhere. My guess is the purge valve also.
Please confirm the 3/8 black line is from the 110v compressor. We talked on the phone about how to confirm that.
When confirmed, turn on the 110V compressor, if the purge valve is leaking you should feel it or hear it at the bottom of the dryer assembly. The reason I am suggesting using the 110 compressor instead of cranking the beast is that hearing is a bit easier without the Detroit rumble.
Is is possible you have the control lines to the dryer reversed?
The fact that your brake pressure gauges remained at 50 tells us your Pressure Protection Valves are working.
Further diagnostics would be to disconnect the air line from the engine compressor, and crank the engine. There won’t be any doubt if air is coming from the compressor or not.
