Fuel pump big enough?

I'm about to get and install a rebuilt Nikki carb. The carb has:

Primary ventury: .980 inch inside diameter

Primary fuel jet: #160

Primary air jet: stock size

Secondary Ventury: stock size

Secondary fuel jet: #190

Secondary air jet: stock size

I have a Purolator fuel pump, 2-3.5 psi, 1700 cc/hour. The pressure is basically stock, the volume is more than the 1400 cc of the stock pump. Will this pump be enough to keep the carb supplied with the fuel it will be able to consume, even at WOT? Engine has a RB size streetport.

just get a holley red....IMHO carter pump is a JUNK-so much incosistency in the pressure. little louder than a carter but you will end up with a loud exhaust anyway...so who cares.
