Looking for the location of where the supply air tanks might be located on Coach #375 (1995). Original problem was the coach would not pump up above 70 psi. Replaced air governor and PPV, now I get above 100 psi, but as I turn off the coach my supply air goes to zero within 5 minutes while my brake pressure holds. So, I I'll start at the supply tanks and work from there, as I still don't an air leak. I've used an external compressor to eliminate the noise of the motor. Open any ideas.

Thank you as always for your insight.
