I wouldn't suggest the clear vinyl tubing. I just went about replacing the fuel lines on my sled with a the basic clear vinyl fuel line, and after about a month, it is no longer real flexible. The reason I replaced it in the first place was because the old lines were so hard, they actually shattered like glass when I went to remove them to get at the carbs. I'm sure I'll be replacing them once again after the season is over. I've heard the lines with a yellowish tint are pretty durable as is the blue polyurethane fuel line.
