Description
Description
Upgrade the fuel system on your Nissan RB25DET with the Radium Engineering Top Feed Fuel Rail Conversion Kit. Designed specifically for the non-NEO RB25DET, this kit converts the factory side-feed injector configuration to a modern top-feed setup, opening the door to a much wider range of high-flow aftermarket fuel injectors.
The Radium fuel rail features a large 0.69-inch internal bore designed to support demanding performance applications. Four 8AN ORB ports provide flexible options for fuel feed, return, pressure regulation, fuel pressure monitoring, and other fuel-system accessories. Unused ports must be plugged.
Manufactured from extruded 6063 aluminum, the rail is CNC machined and finished in black anodizing for durability and corrosion resistance. The system is also compatible with E85, making it well suited for high-horsepower and alternative-fuel RB25DET builds.
Two sets of thermally insulating mounting spacers are included, allowing the rail to accommodate two common top-feed injector heights. Tall spacers support 48mm injectors with 14mm upper and lower O-rings, while the short spacers support 34mm injectors with 14mm upper and lower O-rings.
