Radium Engineering fuel rail (Honda 99-04 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.

Ports and fittings:

It is compatible with all fuel types including popular alcohol mixtures such as E85. It is also designed to work with OEM fitment fuel injectors.

The factory fuel pressure regulator can be used or the port in that location can be used for a 1/8" NPT fuel pressure gauge, transducer, plug, etc.

This kit eliminates the OEM fuel rail cover and also replaces the air pump system hard tubes with vacuum hose for a cleaner appearance.
