I believe you mentioned that the on board (electric) air compressor would not keep up with the leak without the engine running, that would seem to point to a massive leak. You also mentioned the 'kinking' of the air line to the toad when you drug the rear end about the time the massive air leak started. I would pay particular attention to the air line that feeds that connection and confirm there isn't a problem along the path of that air line.
