Radium Engineering 6.0L W12 Fuel Rails (Audi / VW / Bentley)

Each Radium Engineering fuel rail is manufactured with dual 3/8" (6AN) internal bores that internally connect to all 12 injectors. Combined, these dual bores are 12% larger than a single 1/2" (8AN) bore. 

The Radium Engineering fuel rails are manufactured with dual 3/8" (6AN) internal bores that internally connect to all injectors. Combined, these dual bores are 12% larger than a single 1/2" (8AN) bore. This system can support all necessary engine power requirements and is compatible with all alternative fuels.

FEATURES

• Lightweight aluminum construction
• Single 8AN ORB ports at both ends of each fuel rail
• 12% larger internal flow diameter than 8AN
• Anodized finish for wear and corrosion resistance
• No special tools required for installation

FUEL INJECTOR COMPATIBILITY

Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors (or any equivalent aftermarket injector) can be used. Aftermarket injectors must match the OEM height and O-ring dimensions. Radium does not make injector recommendations other than "OEM equivalent".

INCLUDES

• Billet 6.0L W12 Fuel Rails (x2)
  
• Preassembled O-ring Sealed End Caps (x4)
• M6x1mm Stainless Steel Hardware (x6)
  

PORTS AND FITTINGS

The O-ring sealed billet end cap ports are 3/4"-16 thread tapped compatible with 8AN ORB fittings.

• 8AN ORB Adapter Fittings 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.
