I have an electric fuel pump now.. I broke my first mechanical after about 1000 miles.. I needed to keep the pressure low so I went with a carter fuel pump.. It pushes 4-6 PSI and is super quiet. You never hear it running when the car is idling. I have a toggle switch in the cockpit to shut it down and an
oil pressure switch in case of accident which then shuts down the relay. Be sure to go from hard line to rubber before the pump so you cut down on vibration.
