You have a TR4A / TR250 / TR6 tank. These tanks are vented via the cap
instead of via a draught tube. (The may even have started doing this by
late TR4; someone else may have a more accurate answer as to when the
changeover from vented-tank to vented-cap was made)
I have a '62 TR4 and it has a vented gas tank. As I am nowhere near the
original owner, I can't say that it's the original tank (but I sure had a
lot of rust removed from it... chances are, it is) The vent was a banjo
fitting and a tube that went down through a hole in the body and pointed
at the ground. I don't think it does much overflowing, a little gas might
get out on hard corners with a full tank, but I seem to remember a bit of
a baffle on the tank-side fitting, guess that stops most of the splashes
from coming out.
