The best way I know is to drop the tank, pull the sender and get a mechanic's mirror inside and look UP, that's where the bad rust will be. If you have any doubts about your local re-nu provider you can take the tank to a chem-strip place first, then to the Re-nu shop. I have used the Renu process on several tanks and have always been completely satisfied with the results.
Seeing chunks of rust is like seeing ants in the house--if you see one, there are more where you can't see them.
Treat the fuel system as a whole--every part of it is old and will need attention. If I do a fuel pump I will change the flex line (new one from the PAC region that re-pops them) blow out and pressure test the steel line (they can develop pin hole leaks that will drive you insane) and treat the tank. I don't like old cars that break down with wives and other doubting women inside.
