The Radium Engineering 20-0866-PK Fuel Rail Plumbing Kit provides a direct plug-and-play hookup for the Radium 20-0866 Fuel Rails to the OEM fuel system on the Audi R8 Type 4S and Lamborghini Huracan 724 V10. Designed to integrate seamlessly with the factory plumbing, this kit eliminates the need to source individual fittings and hoses for a clean, professional installation.

Barbed fittings are included that mimic the OEM fuel rail connections, allowing the factory rubber hoses from the RH and LH high-pressure fuel pumps to be reconnected directly. An additional set of 8AN ORB to 6AN male fittings is also provided for connecting aftermarket fuel lines if required. A large insulated 8AN crossover hose is included for maximum flow between rails. Adapter fittings are also provided to allow the OEM Bosch fuel pressure sensor to be reused.
