It is possible to get the diesel leaks to stop. On my 1970 4000su the biggest culprits were the fuel shutoff below the tank (as you've noticed on yours), also the line from there to the single CAV filter and on the pump. Old rubber connecting some of those sections, which I believe was original equipment, was also too far gone and always weeping. A similar piece where the excess fuel from the injectors went back into the top of the tank filler.
Bending up a few new lines and putting new rubber fuel line sections in did the trick.. in two years, no more diesel leaking.
The last leak is from the bottom of the bell housing (hole with cotter pin), and I guess I have to split the tractor to fix that one. Haven't yet figured out for sure but I think it's UTF from the 8-speed transmission. Engine oil level doesn't change, not sure yet if trans. or rear oil level is changing but suspect it's getting lower. The leak isn't bad enough to make it real obvious yet.
