I think this is a good way to upgrade the necessary increase of fuel pressure without getting too invasive. Have had several people have issues with external fuel pumps having problems pulling fuel from the tank. They push like hell but fail on the pull side. The surge tank uses the same volume required for stock systems but will support somewhere around 900 hp with the pressure provided. As long as your manual pump is pushing fuel into the tank you will never run the pump dry. Pretty cool concept that gives you drive ability with reliability.
