GMONIZ adds, "Tim had posted THIS ONE from a 1954 1 ton Panel. Chevrolet called it an 18 gallon tank."
Sure does look like the one I bought. I calculated the gallons based on cubic inches. Comes out about 19.1 gallons. However, you cannot fill a tank up completely with the filler neck down below the tank top, not easily anyhow. Probably is an 18 gallon for actual usage.
Boy howdy, those old trucks continue to surprise me. Just when I think I have a good handle on all of this, here comes a monkey wrench flying at my head. Usually that would be my girl.
All of you, I am responsible to say, "Thank you." Really have learned a lot from this discussion, glad I was wrong on this, worked out much better for all of us.
