Radium fuel rail plumbing kit is designed for use with the Radium 20-0533 fuel rail and includes fittings, hose and adapters to simplify installation. The kit provides parts to reuse the OEM fuel pressure regulator and streamlines plumbing for a clean bolt-in setup when converting early Mitsubishi 4G63 rails to a top-feed configuration, reducing fabrication time during installation.
