I just used a third line with a second clunk in the tank, and I just routed the third line down thru the cutout at the bottom of the cowl and put a stopper in it. Easy to reach for fill up, and when you see the muffler drool out a little fuel, she's full. Dubro fuel stoppers are a couple cents for 4, and they're plenty to hold pressure for those of you with the cline. Best of all, the feed line has no interruptions from the clunk to the carb.
