air ride suspension

there is only a couple of feet of plastic air line from the air valve (like the valve steam on a tire) and the actual air bag its not as involved as one might think

Do you have a gas engined chassis? What you're describing seems more like that used for supplemental air springs used to add weight capacity to conventional leaf or coil springs, not the full-on air suspension systems used on diesel powered motorhomes. If that's the case, try using soapy water to find where the leak is coming from. You may be able to disconnect the hose at the air valve, cut an inch off and reconnect it if the hose itself is leaking at that point.
