This Radium Engineering Fuel Hanger Feed Kit is a surge-tank system that mounts inside the OEM BMW fuel tank on N54-powered E9x models. The factory pump feeds the surge tank as a lift pump, then the surge pumps feed the engine — adding pump capacity and protecting against fuel starvation. Uses a stainless filter.
