The rust is on the vertical baffle wall which is visible through the
sending unit hole.  It looks very superficial.  Based on what you said
it sounds like it would be ok "as is" after the sealing compound is
applied as this would deprive the rust of air and water.  The
instructions (see link below) say that compressed air through the
pickup will prevent the sealer from gumming up the screen.

The drain plug is infrequently used, but can be quite convenient when
you need it.  The car is a 1972 N. American spec roadster, and the
original tank has a drain plug.   I don't know whether it was factory
or aftermarket fit.
