Radium Engineering Top Feed Fuel Rail Conversion Kits Fits VVTI and non-VVTI Engines
Radium Engineering offers top feed fuel rail conversion kits for specific applications. Manufactured with a large 0.69 in. internal bore, the fuel rails can support all necessary engine power requirements. They are CNC-machined from a custom 6063 aluminum, media blasted, black anodized, and laser-etched for a high-quality surface finish. These kits are compatible with all fuel types, including popular alcohol mixtures such as E85.

The Radium fuel rail converts the OEM side feed fuel injector setup to top feed, allowing the use of high-flow fuel injectors (not included). Each kit includes two different sets of mounting feet, allowing various height fuel injectors to be used. The anodized aluminum mounting feet secure the fuel rail to the intake manifold reusing the OEM thermal insulating spacers. The fuel injector bores and the included press-fit injector seats are designed for 14mm injector O-rings. These seats include O-rings to prevent boost pressure leaks. They're CNC-machined billet aluminum, anodized, and laser etched.
