dirty fuel tank

[Kneale Brownson]

If there's rust inside, the tank most likely is rusting through from the
outside.   It'll probably start leaking soon.   I just replaced the leaking
fuel tank on my 200q20v, and even though the tank looked pristine inside,
there were little bits of rust starting to accumulate that has to be from
the rust-through.

Is this a non-quattro?  If so, it'll be fairly easy to drop the tank.   My
200 is a quattro and it's a real chore to get that tank out.   On my
motorcycle list, there's been frequent reports of success with treating
rusty gas tanks with a product from Por-15   http://www.por15.com/    Read
the tank sealer info completely.  You have to have the tank loose to be
able to treat it the way they describe.    They claim they even can repair
holes with their products.
