It gives the installer a Radium-specific foundation for the listed application.\u003c\/p\u003e\u003ch3\u003eWhy This Upgrade Matters\u003c\/h3\u003e\u003cp\u003eFuel rails become a packaging and flow foundation once an engine moves beyond the limitations of the original fuel system. The goal is not simply a larger rail: the rail must provide the injector interface, port layout and plumbing flexibility needed to build a serviceable, stable fuel system around the engine.\u003c\/p\u003e\u003ch3\u003eProduct-Specific Details\u003c\/h3\u003e\u003cp\u003eThe Radium Engineering high flow secondary fuel rail is for the 13B-REW rotary engine. The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. This fuel rail includes injector seats and converts to feed fuel injectors (not included).
