Radium Engineering Fuel Hanger Surge Tank - Audi R8 (42 / 4S) / Lamborghini Huracan
The Radium Engineering Fuel Hanger Surge Tank (FHST) is a drop-in fuel pump solution for the Audi R8 and Lamborghini Huracan (SKU 20-0860). It supplies a port injection system independently while the OEM direct injection system, pump, filter, regulator, venturi jet pumps and fuel level sensors stay untouched.
The FHST drops into the left-hand tank opening, opposite the OEM pump, and keeps a trapped reserve of fuel around the aftermarket pump to prevent starvation and cavitation. The canister is fed by the left-hand OEM venturi jet pump (tested at 302LPH), return fuel from the external regulator via an anti-foaming diverter, and three one-way fill valves flowing a combined 1,065LPH. Separating port injection also removes the restrictive orifice fittings the Huracan/Type 4S uses on its port injection rails.
Note: Fuel pump sold separately. Keep at least half a tank of fuel during track use. Gen 1 R8 (Type 42) and Gallardo require the Radium 20-0865 port injection fuel rail kit and 20-0867 plumbing kit; consult your tuner for Huracan and Gen 2 R8 plumbing. Radium relay kit 17-0031 is recommended to power the pump. Installation by a professional is recommended.
