Manufactured with 0.69" large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements. CNC machined aluminum mounting tabs are included for a factory fit and to maintain the original fuel rail height so both OEM or aftermarket equivalent injectors can work. The fuel rail ports are tapped for 8AN ORB. Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

Each fuel rail features two 8AN ORB threaded end ports (4 total). The two fuel rails and all necessary mounting hardware are provided, as shown. Fittings and hose will need to be individually purchased.

NOTE - Not compatible with dual-VVTi engines

Injector Compatibility

This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.
