My Savannah kit came with a preformed nylon tube used for this purpose.
I like it because it is simple and effective, and only has two joints;
the points of attachment to the tank. The bends were heat formed, I
guess. I don't know what grade of nylon is used, but it is sort of
miky white, but gas is easy to see in it. Nylon is used in lots of
fuel system parts in automobiles, so this seems like a good choise.
