For those of you that have never changed out an air governor, here are a few pictures:

To adjust your pressure, under the rubber cap is the adjusting screw

Installation complete

Some governors are remote mounted, but mine is directly bolted to the compressor. The governors are cheap, this rebuilt unit was 16.00. I got mine at Fleet, but most truckstops and parts places have them. There are different types and pressures, just make sure your part number is the same. I changed it as a PM item while chasing an aux air leak. This took about a half hour, mostly because you have to R & R your fittings as the governor does not come with fittings, only plugs that need installed in the unused ports.

Even Jeep could do this!
