RE: ISRI Seat Lumbar Valves
Al,

In my case it was the valves themselves that were leaking. The two lumbar switches are the valves. Not fun nor easy to replace, but I got it done and the leak is gone. The tubing was fine. I just snipped off 1/2" of the stretched out ends where it plugs into the respective valves. The plastic tubing under your seat is probably fine too. It's well protected from sunlight and the elements. There were a number of seat switch/valve assemblies used. The only way to find the right one is to photograph it and send it to Prevost Parts for a match.

Ken, welcome to the forum!
