Product Description

The Radium 20-0230-PK is the factory feed line plumbing kit for the Radium 20-0230-02 K-series fuel rail. It allows direct connection to the stock Honda fuel feed line without modification, using an extended SAE quick connect fitting engineered to clear the OEM coolant hose where equipped. Two port plugs are included to cap the remaining unused 8AN ORB ports on the fuel rail for a clean, leak-free installation.

This kit is intended for builds retaining the factory fuel feed line. Applications requiring custom fuel plumbing should source 8AN ORB fittings separately and omit this kit. Compatible with gasoline, E85, and alcohol fuel blends. Not compatible with the direct-injected K20C1 engine.
