This is THE common denominator for us all, well except Wally. We chase air leaks all the time. For all except one, the culprit has been the quick connect push on fitting. Magnified examination of the tubing and the fitting shows that the tubing develops a depression where the grasping ring of the fitting contacts it. No surprise the tubing is nylon and will deform over time. Sometimes merely trimming 3/8 inch off the tubing and reinserting will fix the leak. Temporarily. I take the time to use DOT compression fittings. I have not had to refix one of the compression fittings ever.
Also, do use pipe dope or loctite sealant to put on the threads of the new fitting instead of Teflon tape. Teflon tape can put little pieces of tape into your air system that can migrate to valves or other orifices and stop them up.
Just my .02
Oh yeah, one more thing. The air leak detector that Steve uses. I bought one, and was convinced it was worthless. I learned that if I used ear muff headphones and used it to listen for leaks that it was very effective.
And a curiosity question for Wally. When you replumbed the air system on your coach did you use push on or compression fittings?
