Applying here to the pneumatic system

My signature coach has a leak somewhere as most do that used to take a week now it’s a day is there a way to air the system up with a via air’s compressor limiting the amount of pressure of course and what would the pressure be and would you use the nipple in the front of the couch next to the generator?

Next to gen on ours is the air fill no check valve. But the air from the air compressor is not ran through the air dryer so drain them tanks.

Depending where your leak is, it may not be getting air pressure until it surpasses the PPV limit, likely somewhere around 60 PSI. Inflating those tanks is a big job for a little viar compressor if that's what you meant.

What I would do is fill the system with the engine compressor then use the Viar ( sp ) comressor occasionally to keep the pressure up as you search for leaks.

I use the air fitting next to the gen sometimes but never when it's humid.

There is a thread on IRV2 about leaks and Timaz recommends this ultra sonic leak detector.     I'll probably order one when I get back from our short trip.
