Have a 1986 Maxi that had a rather rusty fuel tank when I bought it. At first I removed the petcock and with an empty tank and as piece if welding wire with a small loop in the end managed to fish out a bunch of rust. Kept flushing and felt I had gotten most of the loose stuff out. Then did an apple cider vinegar/salt flush letting it sit for several days. It looked much better so added a quart of rubbing alcohol to asorb the water and then blew it out with air till dry. Today I put in a new petcock and some gas and took it for a ride. Seem to run fine. Parked it and about an hour later I noticed a dark patch under the bike. It was gas and dripping a 2 drips a second. It seem to be coming from the very bottom of the tank near the weld. I drained the little gas that was left.
Now what to do. Is there an epoxy coating that I can put in the tank and slosh it around and seat up the leak?
