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.
Overview
Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. This kit is 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). The kit includes 2 different sets of mounting feet allowing various height fuel injectors to be used (short spacers shown). The anodized aluminum mounting feet secure the fuel rail to the intake manifold reusing the OEM Toyota 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 are CNC machined billet aluminum, anodized, and laser etched.
Fuel Injector Compatibility
This fuel rail kit is compatbile with aftermarket universal fuel injectors with 14mm upper and lower O-rings. Two different sets of fuel rail mounting brackets are provided to accomodate 48mm and 34mm fuel injector heights.
Notes: many aftermarket injectors have colorful aluminum caps that change the height and/or upper O-ring size. In most cases these adapters can be removed and the bare injector will be compatible with this fuel rail.
