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.
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, black anodized, and laser etched for a high quality surface finish. For flexibility, the fuel rail features three 8AN ORB ports and is compatible with all fuel types including popular alcohol mixtures such as E85.
Notes: This fuel rail is compatible with early model 1JZ-GTE VVT-i engines only. It is NOT compatible with late model 1JZ-GTE VVT-i engines as the fuel rail creates an interference with the ETCS-i throttle body drive-by-wire motor.
The Radium fuel rail is compatible with the OEM 1JZ-GTE VVT-i top-feed fuel injectors and any aftermarket injectors that fit the OEM fuel rail. Injector bores are 11mm.
The fuel rail re-uses the factory mounting bolts and plastic spacers. Make sure these are present before beginning installation.
To reuse the OEM fuel pressure regulator, select the 14-0285 8AN ORB to M12x1.25mm Fitting (shown below).
