NE Kansas | I have an older Peterbilt 379 that last fall I put a new governor on air compressor and since then the air dryer seems to pop off every 20 seconds or so which is pretty annoying. I had to adjust it so it would not build up more than 120 psi but I didn't think there was a low end to cut in to adjust? Once the air is up it hardly lowers from 120 unless braking. I don't detect an air leak that's very bad, did I get a faulty air governor or something else going on? | |
