From the little door on the pump panel, looks like yours might be a piston pumper. I have a 1964 Chevy with the 500 gpm piston pump. I think I might have schematics for it. They are a pretty simple pump that don't need a lot of maint. and are really simple to operate. Contact me by private email if you want to chat about some particular items.
