Hi Joe, Glad toy "returned to your project" (and this forum) Good luck getting her..it back on the road again. I don't have a gas tank, but I am pretty sure you can find one at Desert Valley Auto Parts (dvap.com). I don't know if a tank from just any "senior" Kaiser will do, but I suspect that K-F used the same tank on all 47-55 models (Someone please correct me if I'm wrong).
