I found a local shop that took my line and tested it to verify the leak location. Although I couldn't see where it was leaking, it was where I thought it would be - where the hose ran across the top of the frame. I guess the outer fabric layer didn't show the wear, but that layer must have worn into the rubber behind it. Anyway, the shop then cut out the bad section and put 2 fittings on that were then connected with a nipple. I installed it last night and I figure I won't be having this problem again. The fittings are now sitting on top of the frame, not the hose. I'll be dead and gone long before the frame wears through those fittings. If I have a bad experience trying to find a part, I always keep looking and find a spare to put in my parts bin. Since I don't want the entire fill system - just the hose I'll contact that EBAY seller to see if they'll send me just the hose and fittings. Thanks for the help.
