I have on old pickup, dodge-200 1962, that someone has added saddle tanks
to. I have not used these tanks so the gas in them is atleast 15yrs old.

Take them to a radiator shop and have them hot tanked.
Oh,....let them keep the varnish.

Best advice so far. It's not that hard to drop the tanks. You will also have
to inspect the level sending units.
"Hot tanking" is what the professionals do for a good reason.
