Radium FHST Extension Add-On, Audi R8 Type 4S / Lamborghini Huracan

Application: Radium 20-0860 FHST in the Audi R8 Gen 2 (Type 4S) and Lamborghini Huracan
Part Type: FHST extension add-on
Part Number: 20-0868


The Radium Engineering 20-0868 extension kit adds about 0.2L (7oz) of fuel capacity to the Radium 20-0860 fuel hanger surge tank by using a 39mm (1.5in) deeper canister. The extension section mounts between the canister and the bottom cap, locating the bottom of the FHST to clear the fuel level sensor.

Longer tubing and a longer pump bracket are included to keep the fuel pump inlet at the bottom of the surge tank, and a stainless steel mount secures the OEM venturi jet pump out of the way. Radium strongly advises fitting the extension to Huracan and Gen 2 R8 installations so the FHST reaches the lowest parts of the tank.
