Gas tank cleaning

[SuperNovaSS]

24 hours should be ok. You can also water it down if you are concerned. If it is varnish and not much rust, you may want to start with gasoline, lacquer thinner, or other solvent. Then you don’t have to worry about the time. Vinegar is an acid. You can handle this by yourself.

Thanks again for all the replies. These ideas will be very helpful. I'm going to do it myself as the gas tank is the original and I'm preserving the car. I will attempt to post some before and after photos to show my results.

Thanks again for the great information.

Regards,
Marty

I believe radiator shops used sulfuric acid when cleaning out fuel tanks. Eastwood sold a kit for cleaning and sealing gas tanks, check them out.
