1. After cleaning out the basement storage bay where the leaking air line was thought to be, and chocking the tires to prevent the coach from moving, the real work could begin.
3. Since the tray is located at the top of the frame rail, getting inside is very difficult. The only access you will have is to reach into the tray and carefully move the various air lines around until you hear the sound of the leaking air change. Then you will know you are moving the right one. Once you locate the correct hose you will have to fish it out to the top so you can repair it; usually there is enough slack in the hose to do this without damage. While the hose is still in the tray you can hopefully feel the escaping air with your fingers so that you are sure you located the right one. In instances where you can hear the leak but can’t see it, a spray bottle containing a water/soap solution can be a great help. Once the leak is located, use the air reservoir tank manual water drain valve (if available) or a manually accessible air pressure release valve to bleed air pressure from the system before cutting into any pressurized lines or unscrewing any pressure fittings — or serious injury could occur.
