What I want to know is, how do you get all that brass tubing going in all kinds of directions into the tank in the first place .

(I hate putting together fuel tanks, and I've taken to using a normal clunk line for the fill/drain instead of brass tubing going to the bottom of the tank. Other than that, I tried a dubro fill thingie once, and one other brand of fill thingie years ago, and I quickly decided that they just aren't reliable enough for me).
