Rescuing the 51 Farmall M that I grew up on. Unfortunately, the second owner abandoned it to the elements for somewhere between 5-10 years. The gas tank had a lot of gunk in it, so I poured in a gallon of acetone to see what would dissolve. The only leaks were found when I turned it up onto the front side. These leaks are in the UPPER stamping on the front. I thought that was a bit strange. At any rate, I am asking for your experience to see how to fix this tank. It has zero dents although there is a fair amount of pitting on the (exterior) top side. Assuming that sealer would be adequate for the inside. I will have a body shop do the sheet metal, so media blast would likely be done. But is there a particular order in which repairs should be done? In this part of Ohio, tanks are hard to come by. Salvage yards are not carrying much of anything from Farmall Letter Series. Any advice would be greatly appreciated.
