No I haven't contacted them yet, I was waiting to see if the shop that set up my diff came up with any ideas yet. When I called the shop earlier today he was about to try his fix, he had had another customer call today with the same problem. I picked up some 1/8" crush sleeves that I haven't had a chance to see if they fit. If the crush sleeves are to big I was going to try a piece of the blue airline. I will have an idea tomarrow whether or not there is an easy fix. Another idea would be to flare the end and use a gas fitting at the bulkhead, though the tube on mine is nolonger long enough for that.
