PORTS AND FITTINGS
The fuel rail ports are tapped for 8AN ORB.
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.

FUEL RAILS
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 (8 in total). 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.
20-0866 only includes the fuel rails and the mounting hardware, making it ideal for custom applications.
Extra fittings, hoses and other fuel plumbing items will be needed to complete the installation. For custom applications, that demand a fuel pressure regulator and/or fuel pulse damper, a good location is on the right rear ports, as shown below.
The fuel rail is compatible with all fuel types including popular alcohol mixtures such as E85.
Optionally, a combination of adapter fittings 14-0119 and 14-0359 can be used for reusing the OEM pressure sensor (shown above and below).
