There are no seals on the shaft. There are two areas of potential
leakage: The gasket between the sending unit body and the tank, and the
gasket under the sending unit cover.
On old units the mounting flange tends to be warped from overtightening of
the mounting screws. You can sometimes dress it down with a file, but
this thins the flange, making it even more prone to warping. A thick,
well cemented gasket will usually solve the problem.
The steel cover is also likely to be warped from overtightening. This can
be dressed down without costing much strength. Again, a well-cemented
gasket is required.
Don't worry about lack of seals on the shaft. The shaft was never meant
to be leakproof. Fuel will get into the switch area no matter what you
do. It's up to the cover gasket to keep it from leaking out.

If cars had evolved as fast as computers have, by now they'd cost a
quarter, run for a year on a half-gallon of gas, and explode once a day.
