My supply gauge was erratic and wouldn't pump up and I knew I didn't have a leak big enough for the supply side not to release the emergency brake at around 65 lbs. The only leaks I have had this big were a cracked height control valve and the hose coming off the Aux compressor broke. I replaced the big air dryer filter behind the driver's side tag and drained my tanks and the problem was solved. I then installed the air dryer with the electric solenoid on the Aux compressor. Now when the compressor stops, the valve opens and drains the water out of the bowl. In our humid climate the bowl could fill in a day. So far so good.
