The Radium Fuel Hanger Surge Tank add-on converts a compatible Nissan fuel pump hanger into a Fuel Hanger Surge Tank (FHST) for S14/S15/R33/R34 platforms. Intended to prevent fuel starvation during aggressive driving, the kit adds internal capacity and plumbing to stabilize fuel supply under high lateral or acceleration loads. It’s sold as an add-on and does not include pumps, requiring a compatible Radium hanger to function.
