My choice would be to use a 255lph pump for EFI and use a bypass regulator set at 8 psi or so. What is neat about the EFI pump is that you can put it inside the fuel tank to make it quiet. They also are designed to run for a LONG time and be reliable. Race pumps like Holley are noisy, not fuel cooled, and have a short street life. The reciruclating system using the EFI pump also keeps the fuel cooler so less likely to vapor lock.
