thanks alot you saved me getting a new tankdepends on the condition of the tank really. If the rust isn't bad, just get a chemical to wash out the tank. it will strip the rust. That might be sufficient. As long as you keep gas full in it, you don't have to worry about rust. I had an old Suzi with a rust problem. I used a POR15 kit. it has a stripper, a cleaner, and then a sealer. it takes some time and patience to do it right, but it's not complicated. I did mine over about a week's time. I wanted to be sure it was clean and done RIGHT.
As for protecting the carbs and engine, put an in-line filter in the gas line. it'll trap the rust pretty well. you should be able to get them at most auto parts or hardware stores.
whats the best way to get all the styff out of the tank. cuz where the lines go in theres a little lip.Glad we could help you out!
by the way, if you go the route of the POR 15 kit, during the rinse phase, while using water, rinse it REALLY well. I think I rinsed my tank about 30 times with water before little black bits stopped coming out.
Like I said...be paitent with it so that you only have to do it once.
