Radium - Fuel Rail OEM Plumbing Kit for Mitsubishi EVO 4-9 (4G63)

The Radium Engineering Fuel Rail OEM Plumbing Kit is engineered to seamlessly integrate the Radium Engineering Fuel Rail (Part #20-0119-12) into the factory fuel system of the Mitsubishi Lancer Evolution 4G63. This standalone kit allows owners who already possess a Radium fuel rail to connect directly to the OEM hardlines and retain or adapt the factory fuel pressure regulator (FPR) without custom fabrication.
