Don't worry about the inlet filter (IMO). It may be the original owner (who put the new tank in?) just transferred the inlet filter into the replacement tank. Those filters (nylon screening) are still available from FORD I believe.
Just get the tank tanked and see what you have. Ethanol blended gasoline will speed the rusting process.
BTW- When one posts here with a beautiful car, it is customary to include photos so the rest of us will be jealous ...
