For a properly planned performance build, the Radium Engineering Nissan VQ35HR & VQ37VHR Fuel Rail Plumbing Kit 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.

Fitment is specific to Nissan VQ35HR & VQ37VHR; confirm the vehicle and surrounding hardware before ordering. Injector height, upper/lower O-ring diameter, and plumbing requirements vary by engine. Match the exact application and injector configuration.
