I think the 47 and 48 gas tanks are hard to find. I have seen them go on e-bay for what I thought were high prices. The whole top of my 48 3/4 ton tank was rusted through with pin holes and the PO had smeared bondo over it as a patch. I cut the top away and used a doner tank to make a patch and repaired it. It took me a day to fix the tank and I wished I had spent more time cleaning out the tank, because I still get crud in the tank. I power washed it and apparently I did not get behind the baffles very well. If I replace it, I will just build a stainless tank for the same location. My 48 half ton parts truck still has the tank in it, but I dont know the condition. I dont know if the halfs and 3/4 tons are the same either. Enough rambling.
