[big gear head]

I have 2 small block fuel pumps. The first one looks like a Carter, but has no name on it. Just a tag with 40468 on it. I would like to rebuild it and use it on the 327 that I'm building for my dad's '55 Chevy. Does any one know what this pump is and where I can get parts for it?

The second one has the numbers 40987 and what might be a date of 21 on it. Does anyone know what this pump is and is it worth anything? I didn't see AC on it anywhere.
