I purchased a used gas tank a few years ago. It looked solid, however having it flushed and cleaned revealed some pretty thin areas. And with re sealing with chemicals etc, it made me ponder just replacing with a new one. So I did. Found it in ebay, and for a pretty good price. So if you have a ’57-’59 Ford/Edsel Wagon or a ’57-59′ Ranchero you should purchase a new tank. They were a limited production run, so once they are out, I doubt they will make another run of them!
The ebay seller is tomsclassic . He has them about $150 cheaper than everyone else. It’s a beautiful tank and liked it so much, I purchased one for my ’66 Fairlane GTA Convertible.
