Here is some photos of my new fuel sending unit for my 1950 CJ-3A;
I ordered the new one from Walck’s 4wd. It came with new cork gasket. The float is not cork anymore.
You need to check if you are using 5 or 6 screws. Recent model use 6 screws.
I’m not sure if my cork float was original or not.
And it is installed!
