Has anyone tried putting white vinegar in a 1927 gas tank to clean out rust ??? If so did it take a long time ?? .. Thanks for any help .. Joe

I used muriatic acid to clean my 1926 cowl tank. Many here don't like to use and advise against it, but I have been using it for 45 years to clean off rust and to me, there is nothing better as long as one uses the proper safety precautions.

After all the rust was cleaned out, I neutralized with a solution of baking soda and water. Once neutralized, I flushed with clean water, then dried using a Milwaukee heat gun to quick dry the interior and prevent the development of surface rust. Once dried and cooled down, I plugged the outlet with a male brass plug, poured in a quart of POR 15, screwed on the gas cap and shook the gas tank every which way until all interior surfaces on both sides of the baffles were coated, I then unscrewed the brass outlet plug and poured the POR 15 back into the original can for future use. You will be surprised at how much you have left. Once I got out as much POR 15 as possible, I cleaned off the threads of the outlet and gas cap opening. Jim Patrick

I'd find a use for the remaining POR, it won't keep long. I used it on another vehicle gas tank that I purchased new and treated it prior to installation. I have a clear in line gas filter on that jeep, and it hasn't turned the POR color after 4 years, so I'm happy with the results.

But when I opened my sealed can of POR 15 a month or so later to treat some wheels, it was very lumpy and starting to cure.
