Title: Fuel tank cleaning
Post by: Coop on October 28, 2018, 01:44:11 PM: Hi guys,
Given my recent issues with a large amount of scale in the upper and lower fuel tanks from oxidization, I have now ordered a new fuel pump and filter from Partzilla and have managed to clean out the lower tank to the point where there is no discolouration of fuel when it is filled.
Whilst I am awaiting the new pump and filter, I still need to clean the scale out of the upper tank.
What methods and/or products have people found to work the best?

If you can find one of those that's long enough to get to the bottom that would hopefully shift any loose stuff. There are anti-rust chemicals available that might be worth applying to the empty tank. I wonder if there's a two-pack product that could be used to seal the corroded surface. Someone else will know.

Definitely the preferred route. Even if it involved a repaint, it would be simpler and safer.

And cheaper than a pannier.

Maybe I could slowly change my ST to red.

Might look a bit harlequin during the transition.

Thanks Brian, luckily I have never had to restore a tank, others I know have, good to know what to use.
