Radium K Series Fuel Rail


The rail features a large 0.69" internal diameter bore to suit even the most fuel hungry engines. They are CNC machined from extruded 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. All 3 ports are machined with -8 AN ORB Ports (3/4"-16 female) threads. 

Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused and Phenolic washers are included to thermally insulate the fuel rail from the aluminum intake manifold.  

Kit Includes:

  • -Black Anodized Laser Etched Aluminum Fuel Rail
  • -Stainless Steel Mounting Hardware
  • -Phenolic Thermal Insulating Washers

Be Sure to add A Radium Engineering direct mount regulator (DMR) for that ultra clean look and less clutter. Know that it can be used if the OEM returnless fuel system is no longer used.
