The Radium Engineering fuel rails have been confirmed to be compatible with the VQ35DE, VQ35HR, and VQ37VHR engine. However, there are other V6 Nissan VQ variations that are very similar.

The fuel rails 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 bottom ports). The fuel rail features 14mm injector bores and is compatible with the OEM injectors and any aftermarket injectors with OEM VQ fitment.

The fuel rails mount with stainless steel brackets and hardware. The unique mounts permit fitment with all VQ engines. Additionally, the OEM injector clips can be reused for the VQ35HR and VQ35DE, as shown above. 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 several different configurations, including parallel, series, or a return system.

NOTE: Because of the OEM intake manifold mounting bosses, two Radium 14-0150 8AN ORB plugs must be used in 1 of each of the center ports for VQ35DE engines ONLY.

As shown above, the base kit (P/N: 20-0458) includes ONLY the fuel rails and associated mounting hardware. NO FITTINGS ARE INCLUDED.
