Manual pump VS stock, does computer regulate fuel at pump?

I'm interested in the answer too, my gut says that the pump pumps full pressure and the regulator controles the pressure to the EFI.

The computer would control the injectors, so like the AC power in your house, you have ~2000 watts available even if you only use 20 watts.

You have full throttle fuel flow and pressure avalible even if you are only at part throttle
