Radium Fuel Hanger Surge Tank (FHST), Audi R8 / Lamborghini Gallardo / Huracan
Application: Audi R8 (Gen 1 Type 42 and Gen 2 Type 4S), Lamborghini Gallardo LP and Huracan
Part Type: Fuel hanger surge tank (FHST)
Part Number: 20-0860
The Radium Fuel Hanger Surge Tank (FHST) is a drop-in aftermarket fuel system for higher-power builds that works alongside the OEM fuel pump. It can feed port injectors on its own, leaving the OEM pump to supply the direct injection system - on the Huracan and R8 Type 4S this removes the restrictive orifice fittings on the port injection rails.
A surge tank collector in the LH tank keeps a fuel reserve around the aftermarket pump to prevent starvation and cavitation at high power. It is filled by the LH OEM venturi jet pump (flow tested at 302 LPH max), returning fuel from the aftermarket regulator via a diverter, and three one-way fill valves. The OEM pump, filter, regulator, venturi pumps and level sensors are all retained for the stock system.
