Went to the bus barn yesterday to load up for a short trip to the racetrack this week. The aux. air compressor was running and I could hear a leak. In the steer bay, one of the 1/4" air lines was broken at a connection for no apparent reason. After shuting down the compressor, I cut off the old compression fitting and replaced it with a quick connect fitting and turned the compressor back on. Air pumps up just fine and I find no leaks at the repair. About ten minuets later, the line breaks again. When I fixed it again, the same thing happened. What I have found so far is that the line that runs back into the coach seems to have lost it's integrity. It will crack and break soon after any pressure is applied. The line that comes from the compressor is fine, it looks like new. The air line supplies air to the fresh water fill valve. Quick fix was to plug the supply line and holler for help. I am running out of line to fix as it has gotten shorter and shorter with each attempt but I have not found an area where the line is still good. Thats bad, I know, so has anyone ever run a new 1/4" air line back to the wet bay in an older Liberty? I think I can live with it for awhile, and when I get time I will call Liberty and get their 2 cents on a fix, but just looking for any help that might be out there. Thanks
