OVERVIEW The Radium Engineering Fuel Hanger Surge Tank (FHST) is a drop-in aftermarket fuel pump solution for maximizing power potential. The FHST system independently supplies fuel to the port injectors, while the direct injection system remains undisturbed using the OEM fuel pump. The surge tank functionality ensures that a fuel reserve is kept trapped around the aftermarket fuel pump to prevent fuel starvation.
