Electrolysis with Tri Sodium Phosphate solution removes rust and leaves a coating to inhibit further rusting

Oh my, plenty of discussion on this. Try a search for threads. Here's just one:

If you are not in a rush to get it done, the best and possibly the cheapest way to deal with rust is to buy a 5 ltr. container of molasis (available from equine suppliers) mix it with 20 litres of water in a large container, I use an old plastic brewing bucket. You could simply fill the petrol tank with the molassis solution if you still have the taps in it. Leave for two weeks then rinse with hot water and dry with a hot air gun or hair dryer to prevent flash rust. The molasis solution will remove only the rust and not attack the steel unlike acid based rust removal products. I have been using this method for years and it really does work. Once the rust is gone you can use any one of a number of propriety tank sealers that are avaible.
