This Nissan RB20DET fuel rail is manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The rail is CNC machined from a custom 6063 aluminum extrusion and black anodized and laser etched for a high quality surface finish. It incorporates many lightweight features to go with the strong integrated gusset mounts.

The fuel rail is designed for any aftermarket injectors that have the same fitment as the OEM injectors. Contact an injector manufacturer to see what they offer. The upper injector bores are machined with a common 11mm ID (Denso). Use the included O-rings if re-using the OEM injectors (shown above), otherwise the included O-rings will not be needed. As shown below, the front, rear, and center ports use 8AN ORB (3/4"-16 O-ring threads) to accept many adapter fittings for custom high flow fuel system builds.


  • Black Anodized Aluminum Fuel Rail
  • Stainless Steel Mounting Bolts (x2)
  • FKM O-rings for OEM Injectors (x6)

Note: This fuel rail does NOT come standard with fittings (see plumbing kit here).  If the OEM fuel pressure regulator will be reused, use the 20-0303 Fuel Pressure Regulator Adapter. Installation instructions available at www.radiumauto.com
