Turns out that the seam on the tank has some bad spots in it. I believe a liner will fix it but for now I just cleaned it out and put it back in the car. I will just keep about 5 gallons in it to keep it below the seam. I will not drive it other than pulling it in and out of the garage. I will decide later what I will do with it. I have a Buick tank that is nearly identical. I can likely swap the neck and move the vent and work just like the original.
