Fuel Pressure Regulator Required?

To help cold starts, I would like to install an electric fuel pump.
My Demon is totally stock with its 198ci and 1bbl Carter BBS carb.
The FSM tells that the stock pressure for this carb is between 3.5 and 5 psi.

If I install a fuel pump like this one (2.5 - 4 psi) :

Or like this one (3 - 5 psi) :

do I also need to install a pressure regulator?

Thanks
