    Could someone explain how after 24h of being parked I found that The gague of the primary tank at 80 psi the gague from the secondary air tank at 0 psi and the cab airbags were empty. I just changed the levelling valve due to a leak and I was told that could be the reason but i my didn't do the trick same problem

    Could be alot of things. Leak on the transmission. Just had a purge valve leak fixed, you had to be laying on the ground next to it to hear it. So your going to look around and listen for it. Get a spray bottle mix water and dish soap and spray on connections.

    Look for a air blower T fitting under drivers seat, ck. the lower part of cab air bags where they flex for leaks?

    Any time you lost air, check your air compressor first before proceeding down the network of air lines etc. If the compressor has quit working, that is your problem right there. If not? Like others said, soap and water and follow the lines until the leak reveals itself.
