I had a similar problem with the barbed fitting, but was able to twist and push it enough to eventually get it all the way seated. It was a freakin' b*tch though. As for the other CS supplied hoses, I couldn't for the life of me get those damn hoses on anything, but then when I called Corksport out of pure desperation, Derrick told me to chew hard on the end of the hose (I used my molars) for a few seconds and try it again. It worked like a charm - they didn't go on "easy" per se, but it was then at least possible to get them on to all the places they were supposed to go.
