Radium Engineering fuel rail (Honda 05-09 F20/F22C engines)

The Radium Engineering 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 8AN ORB (3/4-16 female) threads.

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.

The fuel rail is machined, anodized, and laser etched for a high quality surface finish.
