Fixed my air leak-no I didn't.

To start with-the charts were wrong. I had to open up the floor again to get to the foot valve. Then start taking the delivery lines off until I found the one that had air pressure in it. That led to the tractor abs/traction control valve. If I put my thumb over the leaking line, it would build pressure and start applying the brakes.
Replaced that valve. Bingo! After an hour I still have full air pressure!!
