I figured I didn't have much to lose, it had been patched once before, and it may be weeks before & can strap it to my wheel and drive long enough for some nuts to do much good. Before I submerged it in the electrolysis tank I found an old funnel that a junk 3/8 bolt would fit thru snugly. I then taped it to the tank so that the funnel insulated the electrode from the gas tank and didn't have any chance of touching.
Red to the electrode, black to the brass fitting underneath. Ran it a few minutes here & there when I could, Didn't want to leave it unsupervised just in case. Probably ran it a total of 2 hrs give or take.
The sludge that came out was amazing. Yech! Bolt is pretty rusted up now too. I put in a bunch of hardware and shook it. Looked like ashes in it. Then filled it with water and shook some more. Black water. Repeated the process until the water was clear and got the hardware out. It looks pretty good in there, what little I can see. WARNING: the paint on the outside will be affected by the process as well. Mainly on the top of the tank. DO NOT do this to one you are trying to keep in original condition. No big deal if you're needing to repaint it anyways.
Things to watch for: Make sure your funnel has ridges on the outside or put something between it and the fill hole to let out any Hydrogen gas that may build up. Also, have a slight upward to the tank, with the fill being the highest point. This lets the whole tank be in contact with the water and best able to get the benefit of the electrolysis. You want the tank submerged the whole time.
Is it easier than the nuts in the tank & strapped to a wheel?
I don't know, but I think it took less of my time this way, especially when I haven't been able to find an excuse to be on the tractor and the e-tank was all set up anyways..
