Take your tank to a radiator shop, have it steamed out and chemically cleaned, then coat it with some good ethanol-resistant stuff. Replace all the rubber hoses, blow out the steel lines. Give the carbs a proper off-car rebuild.
Put Stabil or similar in the tank and run it for at least 15 minutes before storage. Then forget about it.
P.S.: The main jets do not clog. It's the idle jets that clog as the orifice is very small.
Doh. You're right.
I'm going the aluminum tank route because they only place left that boils tanks around here charges $150 and doesn't even paint them. Not to mention, whoever built my car took a sledgehammer to the bottom of the tank to get it to clear the steering column, putting the spigot 1.5" above the lowest point in the tank. It's a mess. An aluminum tak will be beautiful and it will never rust.
