Radium Engineering Fuel Rail for Nissan RB20DET

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, shown below.

The upper injector bores are machined with a common 11mm ID (Denso). Use the included O-rings if re-using the OEM injectors, 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.

NOTES

• If the OEM fuel pressure regulator will be reused, select the 20-0303 FPR Adapter HERE
• The rail is compatible with all fuel types including popular alcohol mixtures such as E85

This fuel rail features three 8AN ORB ports, two located at the ends and one in the middle. It also features one 1/8 NPT port.

• 8AN ORB Adapter Fittings can be found HERE
• 8AN ORB Direct Mount Regulators can be found HERE
• 8AN ORB Fuel Pulse Dampers can be found HERE
• 1/8 NPT 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.

NOTE: This fuel rail does NOT come standard with fittings (see plumbing kit below).
