I've never bothered to figure out what the upper hose is for, but I suspect it's a vent hose so that the float bowl can operate properly. I can't imagine that fuel can fill the bowl if air can't escape.

I'd probably swap to a longer and better quality vaccuum hose; you could then secure it with a zip-tie. I say vaccuum hose because it is fuel rated, and because it won't collapse if the hose is ever under vaccuum while the engine is running.

Sound reasonable? :roll:
