He did get under it and traced both lines from the bags to the vacuum manifold on the pump while the compressor was running and the only place it was leaking was from the blown driver's side air bag. It was blown as in it audibly popped, not the traditional slow leak.

I'll update tomorrow when the new bag is in.

Could be a main feed line somewhere who knows. I guess if the driver side replacement doesn't work then I'd chase the line.

Probably would help if he was under it when the pump is running. As I think both lines run along the driver side of the truck.
