Why would you need a clunk on the Fill/defueling line? I have used a 3 line system for years also, and have just run the fill/defuel line to the bottom corner of the tank. it pulls all but about a teaspoon of fuel out. never have had a problem with the lines getting tangled.
Because people love making simple things complicated. Bragging rights?? Gadget nature?? .. your guess is as good as mine [:@]
I have examples (from this very forum) for every one of your fingers and probably the toes as well)
