Try this link: https://www.rx7club.com/forum/showth...t=gallons+hour

Somewhere hidden in that thread is the real answer. Pick and choose.

Any flow figure is completely worthless without knowing the pressure is was taken at. Unless two pumps were measured at the same pressure, you can't compare their flow figures.

Anyone with a Mazda FSM can dig up those numbers.

I can't comment on running an FI fuel pump on a carb engine, but I've heard this is not recommended.

The FC turbo fuel pump flows about 50gph easily, but this is at a little over 2 bar of pressure.
