Air ride

[Dean The ResourcefulNorse]

I have a 75 Avion that has an air tank installed. The way I understand the
air system is my air tank supplies air to the self levelers AND the control
valves, which themselves supply air to/from the individual bags. And there
is a line coming out of the tank to a T, one side going to the valves and
the other side disappearing under the coach.



So when I fill the tank thru a compressor and Schrader valve, the pressure
bleeds off in less than a minute. I can not hear leakage anywhere. My
assumption, knowing what that means, is my feed line to the self levelers is
broken somewhere where I can't hear it.



What say you that have an opinion?

I have individual shut offs and Schraders at each mono bag and use a Ryobi
battery powered air compressor to an external mounted Schrader which works
very well, but I would also like the oem setup to work as well.

1975, so you should have a power level right? It would say power level on the control panel on the dash inside.
What position is the control in Raise? Lower? Hold?
Does it work at all if you leave the external compressor hooked up?

Old air lines tend to get very brittle, they definitely could be cracked and have a slow quiet leak.
new air line is cheap.

I'd chase that line going under the coach, that seems suspicious too
