As an Electrician, I used my battery charger to finish the job. I used Evaporust…expensive. I used Vinegar…cheap. I used baking soda to naturalize the vinegar. Then I used the electrolysis. I used a piece of all thread and wood to insulate the rod from the sides of the filler neck. I connected the negative side of the charger to the tank valve at the bottom of the tank, and the positive side of the charger to the threaded rod which goes all the way in the tank but about a half inch off the bottom. 10 amps for about 6 hrs. and keeping a hose running to keep the foam from hurting the paint, and keeping the tank full, to get the rust at the top too. I’m now running off my tank with filters in the tank as suggested above, and in line before the carb. No problems for six months now. For the mix in the tank I used baking soda, two boxes, and a teaspoon of salt, and fill with water. When full, turn on the charger and watch the bubbles. Don’t smoke while doing this. The bubbles are Hydrogen gas. By the way…rust never goes to a magnet!
