There's a little device called a needle and seat - it's basically a flow valve which is attached to the float - it regulates the amount of fuel that comes into the bowl/carb.

^ 'As long as it is the same pressure and volume as the mechanical one it replaces'

I would install a pressure regulator/return set at ~5psi above the stock pressure. Consider a 'roll over' crash type protection - do you want this pumping fuel in a crash?

Perhaps a good mechanical pump is better if you are not going EFI....
