I use a Fuelab pump and electronic regulator for my EFI. Very slick: the regulator controls the pump speed to meet the engine need without a lot of recirculating fuel and noise.
Now they have a new pump:
Moving Fuel: Fuelab’s Brushless Motor 47403 H/E Series Fuel Pump
Trick new design that I haven't seen before.
