Answer 2

It's best to replace the gas tank and blow out all the lines.

Answer 3

Drain the fuel out of the tank first.  Then drop the tank.  Fill the tank with running water (from a garden hose preferably).  All loose rust should flow out.  That should take care of the majority of the problem.  If the problem persist, just replace the stock fuel tank with a Fuel Cell.  It will be Cheaper and easier to find than a direct replacement, or cutting and welding on the old one.

Answer 4

Check with a local radiator shop they can clean the rust out of it and line it so it wont rust again.Check the price as it may be cheaper to buy a new tank.  You can try to clean it yourself and line it but it wont be as  successful,,,,ujn

Answer 5
