Fuel tank cleaning
« 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?

I've never had the problem. But I know there is a variety of wire brushes on a long twisted wire handle. 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.

Or possibly a second hand tank from a parts bike.

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

And cheaper than a pannier.

To clean tanks on old bikes I fill with vinegar and let sit for a few days, give a good rinse with water and let dry.

Mmmm!  A red one!   ;-*

Maybe I could slowly change my ST to red.

Might look a bit harlequin during the transition.

I’m sure that if you go to a bike shop they can give you some advice re cleaning and recoating the inside of a fuel tank. I remember reading something about using special products to rejuvenate a fuel tank.

There are a couple of products available to coat your tank, Redkote is one which comes to mind however for cleaning the inside, also carbys vinegar is what is used, a very weak acid does wonders and is used by car and bike restorers world wide.

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