Re: Air dryer rebuild Reply #26 – June 04, 2025, 05:28:50 pm Switch the lines and it's working...well kinda.One gauge is reading normal, about 110. I believe it's the rear. The other read normal at first then dipped back down to 75 and after about 5 minutes still didn't shoot back up.The new governor I bought is not adjustable and is rated at 100-120 psi.When I shut the coach off, I'm hearing no obvious air leaks at all. Shot the governor and air dryer connections with soapy water and no leaks.I guess this could be the "Blue Box" issue I've read about....really don't feel like running analog gauges...sometimes get sick of working on this thing but it's the nature of the beast I suppose.
