GK, did you ever get your quick couplers installed ?brought it up @nationals to service guy and he said he knew about it. I bought new hoses. (I was one of the lucky ones with rubing hose) the replace ment hose was about 1/8" shorter on engine side I shortened the worn 1 and put it back on to see and it fixed the clearance prob. So if yours is up against the frame an not worn yet just cut a little off the end and it'll be good. The differance is very small. But it is enough to put it up against the frame.And engine shake wears it out.
