I was on the road today and noticed air pressure dropping. I was able to get off road and investigate. The feed line to the step cover solenoid was leaking badly. This leak made it so that when at idle, the compressor could not gain and pressure went to 70 pounds.

Should this line be supplied by service brake circuit? Seems wrong to common logic. Input appreciated. Thanks Pete
