The fuel rail ports are tapped for 8AN ORB

the base kit (P/N: 20-0556-02) includes ONLY the fuel rails and associated mounting hardware. NO FITTINGS ARE INCLUDED.


With the plumbing kit, a stainless steel mount if provided for the Radium FPR. Low profile 90 degree SAE adapters with PTFE fuel hoses connect the OEM hard fuel lines to the FPR. PTFE fuel lines run from the FPR to the rear fuel rail ports. Two Radium fuel pulse dampers and a pressure gauge are included and all necessary adapter fittings. 

These Radium Engineering fuel rails are compatible with the VR38DETT engine found in the Nissan R35 GT-R. They are machined from 6061 aluminum and anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. Each rail has four 8AN ORB ports (2 end ports and 2 top ports for a total of 8 ports). 

The fuel rails mount with insulating spacers and washers for 100% fuel insulation from the hot intake manifold. The unique lower intake manifold mounting points permit shorter less restrictive rails. Additionally, the OEM injector clips can be reused, as shown below.

With 4 ports on each rail (8 total), it is easy to add fuel system accessories such as a pressure transducer, fuel pulse dampers , etc. There is also opportunity to plumb the fuel rails in parallel or series.
