My 1966 Buick Sportwagon fuel tank needs replacement and I can't find a tank for the wag anywhere. Will the tank out of the same year sedan work? I've checked out pix online and they look similar except the fill tube for the sedan is located in the center (for a behind the license plate gas cap?) instead of on the driver side like the wag. I'm prepared to swap the wag over to a center mounted fill tube and modify/swap out the bumper for a sedan bumper if need be. Has anyone replaced the tank in a wag with the sedan tank, and are there any gotchas?
Take a look at El Camino tanks. I believe they will work for you. I know on Pontiac A body wagons of that vintage that the tank it self is made from the same stamping as a 2 or 4 door car. The difference cam ewhen they punched the holes in them. On a 2 or 4 door they punched a hole on the back center and a wagon it was punched in the front of the left side along with a hole for a vent. So if you have to you can modify a regular tank into a wagon tank. But I am sure that a El Camino Tank is what your looking for.
