Radium Fuel Rail Kit

The physical size and shape of the factory injectors are not found in the aftermarket with a high flowing option. These Radium Engineering 2GR-FSE fuel rails allow the use of very common high flowing Bosch EV14 fuel injectors. Manufactured with 0.7" large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements. Stainless steel mounting tabs (shown) are included for superior strength. 

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. Fittings and hose will need to be purchased separately.

Fuel Injectors:

The OEM fuel injectors are NOT compatible with these fuel rails. The machined ports are compatible with 14mm upper injector O-rings. Bosch EV14 injectors are shown above. 
Because of the tight intake plenum clearance (depicted above), the injectors must be extremely short. Below are some of the many fuel injectors that are a direct fit:

• Injector Dynamics ID1050-XDS-34-14-14
• Injector Dynamics ID1300-XDS-34-14-14
• Injector Dynamics ID1700-XDS-34-14-14
• Injector Dynamics ID2600-XDS-34-14-14

Features:

• Anodized surface finish for wear and corrosion resistance
• Lighweight aluminum construction
• Inner bore diameter: 0.7 inch
• Compatible with aftermarket Bosch EV14 fuel injectors
• Can be converted to a pressure regulated return system
• No special tools required for installation
• Fits under the factory intake manifold and engine cover
