82 Express Tank No Fuel Delivery

Turns out most of my 82’s tank is coated in rust inside. No fuel will pass through the lines but will pass through the petcock. I had it running recently using a rag to completely choke the carb but it ran terrible. Took the delorto off and cleaned all of it out. Carb is spotless. Any advice on rust treating and cleaning out the tank so fuel will begin passing back through the lines? Also the area where the petcock valve threads back on? Any help appreciated!

My go-to is evaporust. Degrease and rinse first.

I used white vinegar to clean my QT50 tanks. I took the peacocks off and let the vinegar sit overnight. Emptied the vinegar, then rinsed with water and baking soda. Came out great. Depending on how bad your tank is, you might need to do it more than once or let it sit longer.

The search feature for this forum is your friend....then more on tank cleaning in the wiki than you may want or need. Just how rusty is your tank? Any pictures?

Yes. I hate auto correct sometimes.
