I'd weld in a new top. Or partial top plate. If you kept the tanks full more often, the diesel would protect the tank top from rusting worse than the sides or bottom. My mild steel tanks are 76 years old and look great.
If you seal the top with a new neck and filler, here's some sealants for aircraft tanks that has to work.
A sealed in patch could look poor to a surveyor.
