I found this at Ricks Restoration in Las Vegas. I pulled it directly out of an old pump in his "Junk Yard" before he shut down around 2019. I have been going through my older stuff in storage and I realized I still had two of these left. The picture of the finished restored tanks is one of the restored fuel pumps that recently sold for $6000. The way they had this was inside of the old gas pump behind one another. I guess when one got older and dirty from the elements outside, they would remove it and the one behind it would be placed forward. These would be safely stored behind the "front" one there for quite a lot of years. possibly like 40-60 years without seeing the light of day. It is made of a mid heavy metal.
