You don't want to use the EFI's electric pump, EFI operates around 40psi and Carb around 14psi. There are carb electric fuel pumps available, I belive most of those are mounted near the carb. Ground it and add a relay to a switched circuit like on the duraspark module.

The relay will allow you to tap into a factory circuit but only use a small amount of current to activate. On the duraspark there is a keyed circuit.
It looks like you have 3 options, two wires into the duraspark and one into the coil. Use one of those or another key on switched wire to trigger the relay and let the relay supply power to the fuel pump.
