The cure (I hope) for the sharp bend in the vent line is a longer hose and loop to make the change in direction easier.
That arrangement makes me wonder: if water gets into the vent line, then wouldn't it act something like a sink trap and thus eliminate the venting function (which you are trying to do with a sink trap, but wouldn't want to do with a fuel vent).
I re-did my entire fuel system (tanks, hoses, filter, etc.) last winter/spring, and although the vent lines have easy runs, the port-side fuel fill has a dog-leg (to avoid the lazarette wall) and I don't know how they had the regular hose making that bend without over-stressing the fill neck on the tank (although obviously they did, somehow). Anyway, I went with the "Michelin Man" style Trident hose (#329) that bends easier for the new hose, but that doesn't come in vent type diameters.
I can't tell for sure from the photo, but is that Trident #305 hose you're using? I used some of that for my outboard fuel line (it had a relatively small OD, which I needed to pass the line into the outboard and to the internal fuel pump), but although I had planned to use it for the whole fuel supply system, I didn't like how easily it collapsed in a bend and so I went with Trident #365 instead. It has a slightly larger OD (not an issue except for that one internal Yamaha line), is heavier duty (longer warranty), and -- perhaps this would be of use to you -- has a tighter bend radius than the #305 (if that is what you used and if you want to try to remove the loop). It's a bit counter-intuitive since the hose seems thicker and heavier duty, but, for example, in the 5/16" ID size, the #305 has a 2.5" bend radius, whereas the #365 has a (better) 1.75" bend radius.
Always interesting to read/see what you're doing to your latest C-Dory.
