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.

This fuel rail is for the Nissan RB25DET (non NEO) engine ONLY. This is commonly found in the R33 Skyline among others. For the RB25DET NEO fuel rail, go HERE.

Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The Radium fuel rail converts the OEM side feed fuel injector setup to top feed allowing the use of high flow 14mm O-ring fuel injectors (not included). This kit is compatible with E85.

The fuel rail has four 8AN ORB ports that can be used for fuel inlet, outlet or for plumbing option accessories. All unused ports must be plugged. 

The rail is extruded and CNC machined from solid 6063 aluminum and black anodized for a high quality surface finish.
