20-0866 FUEL RAILS, AUDI R8, LAMBORGHINI HURACAN

Manufactured with very large 0.7" internal bores, the fuel rails can support all necessary engine power requirements. They are CNC machined from 6061 aluminum, anodized, and laser etched for a high quality surface finish. Each fuel rail has four 8AN ORB ports. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors, or any equivalent aftermarket injector, can be used. As shown below, the factory injector retaining clips can be reused.

FUEL INJECTOR COMPATIBILITY

These rails match the OEM injector bores and rail position meaning OEM fuel injectors, or equivalent aftermarket injectors can be installed. Aftermarket injectors must match the OEM height and o-ring dimensions. Radium does not make injector recommendations other than "OEM equivalent". Consult your injector supplier for more information.

PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB fittings.

• 8AN RB Adapter Fittings can be found HERE
• 8AN ORB Direct Mount Regulators can be found HERE
• Fuel Pressure Gauge Adapters can be found HERE

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
