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. 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 below. Because of the tight intake plenum clearance, the injectors must be extremely short.

While many injector manufacturers will make and supply an injector with the required dimensions, these examples from Injector Dynamics are compatible:

• Injector Dynamics ID1050-XDS 1050.34.14.14
• Injector Dynamics ID1300-XDS 1300.34.14.14
• Injector Dynamics ID1700-XDS 1700.34.14.14
• Injector Dynamics ID2600-XDS 2600.34.14.14

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 and will need to be purchased separately. 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.
