The Radium Engineering Toyota 2GR-FE Fuel Rail Plumbing Kit is designed so it connects the compatible Radium hanger, rail, or fuel-system component to the rest of the feed and return plumbing. The application-specific hose and fitting layout reduces guesswork when converting from factory lines to an AN-based performance fuel system.

For Toyota 2GR-FE, it is intended to integrate with the vehicle-specific layout rather than serve as a universal substitute. Injector height, upper/lower O-ring diameter, and plumbing requirements vary by engine. Match the exact application and injector configuration.
