Re: psi a pump delivers, it's really more about how it's installed. Just looked up early carbed T fuel line routing, and it looks like there is a return line. Easy enough to replace the pump with a higher volume one. With an open/unregulated return line, fuel pressure will be pretty low, like 3 psi or less. This will be true even if you use a high pressure MFI or EFI pump - the pressure comes from the regulator. I've heard that some just run with the open return line. Or you can add a fuel pressure regulator.
