Well if you got it from Dave, you got the right stuff, if you're only issue is the hose not "seating" on the fitting, you've got no worries, the stuff on my boat didn't bottom out, I called my supplier and he assured me that as long as you get both barbs in the hose, with a little hose past the closest barb, you'll be fine. That's what I went with, the fuel line stuff went on like butter, the water lines are a little, about 1/4" shy.
