<< I have swapped the ZS Carbs of my '74 TR6 for SUs. I'm at a loss with the
fuel line setup of the new HS6s. There are 2 tubes on the float chamber
lid, obviously one is for the fuel line but what is the use of the second
tube. My guess is to connect the 2 carbs but for what reason? Which is
which? Help. >>

SU H6 (TR3) carbs are as you describe. The second tube is, I believe, an
overflow which is normally directed toward the air cleaner. There is normally
a short (1-1/2" or so) length of rubber tube and then a short length of steel
tube bent about 80 degrees or so.
