The Radium Engineering 94-97 Mazda Miata/MX-5 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.

This version is designed around 94-97 Mazda Miata/MX-5, so the mounting, routing, or connection details should be checked against that application before installation. Injector height, upper/lower O-ring diameter, and plumbing requirements vary by engine. Match the exact application and injector configuration.
