Tim,
The carb is a Rochester Monojet. It's not Carb King's favorite but it's worked well enough for me that my Carter YF 2100S has waited for years on the shelf. (No, I won't sell it.)
I have a second in-line fuel filter on the other side of the motor. That's the one I change routinely. I could buy a Fram filter that screwed into the carb in 2004 but I haven't checked lately. Maybe I should!
I now have an electric wiper motor but the manifold vacuum was a "fore pump" for the fuel pump vacuum port. Here's a diagram of how it was set up.
