I have 2 early tanks in the garage. One from a 64 T-34, and one I just
got. to replace the T-34 tank. I will look in both this afternoon, and
confirm or deny whether the early tanks had the cup.
I can even cut the top out of the original tank and take a picture,
because the whole top around the filler neck is rusted out.

The FI tanks have the return fuel pipe from the engine coming up right
in the middle of that port in the cup. It gives it a syphon effect, to
help ensure that there is gas in the cup until you run completely out.
