Good morning to all,
A few seasons back I switched to a Magna Fuel pump and the Bigger Holley Regulator, I think the part number is #704 and it has a green colored diaphragm which is alcohol resistant. I have 5/8" fuel line from tank to regulator and 1/2" from regulator to carb ( Q-Jet). Checking fuel flow at the carb fitting I can pump 2 gallons of fuel in 30 seconds set at 6 lbs. of pressure. I hope that helps, the bigger regulator has larger diameter orifices internally which should help for fuel flow.
This is probably over kill in my stocker but might help your combination.
Have a Good Day.

Respectfully,
