Unfortunately, I only have a small portable air compressor that I don't believe will pump enough psi, but I'll give it a shot. The 110v compressor runs but doesn't get any air into the supply tank. My 12v compressor was disconnected some time ago as it leaked a lot. I'm leaning towards a blockage of some type. The puzzle is that it airs up the brakes but nothing in the leveling system. I may have to borrow a larger compressor. I'll keep posting until I discover the culprit.
