while its on my mind, I just changed my hose and found the rear exchanger had tweaked upward from ice chunks and eventually cut the hose from inside. the bungs are like 1/2" apart. I think if I deal with it again, I will chop an inch or so out of the exchanger just at the bung and have it tig welded and use a longer hose. you have to pull the exchanger anyway. should give it the flex it needs. maybe a cover too, but a cover wont keep it from getting wacked out of line. as a bonus the hose could be done without pulling exchanger.
