Prevent fuel starvation and support high-power builds with Radium Engineering Fuel Surge Tanks (FSTs). Designed to keep the high-pressure pumps supplied with constant fuel, FSTs store a dedicated volume fed by the OEM lift pump and returned fuel from the regulator. This buffer eliminates starvation during hard cornering, acceleration, or low-tank situations—especially on vehicles with poor factory baffling. Fuel surge tanks also provide an easy upgrade path for forced-induction and high-demand applications without modifying the OEM tank. Ideal for turbo, supercharged, and track-driven vehicles needing consistent, reliable fueling.
