PORTS AND FITTINGS
The fuel rail ports are tapped for 8AN ORB.
8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators can be found HERE.
8AN ORB Fuel Pulse Dampers can be found HERE.
Fuel Pressure Gauge Adapters can be found HERE.
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.

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.
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
