This fuel rail features four ports (both ends and two on the bottom) that are female tapped for 8AN ORB fittings. However, the front port is not useable unless the OEM engine harness is modified.

INCLUDED
20-0371 FUEL RAIL, TOYOTA 2JZ-GE
This part contains the following items:
-Black Anodized Laser Etched Aluminum Fuel Rail
-Injector Seats for Toyota Air Assist Manifolds (x6)

The Radium fuel rail for the 6-cylinder Toyota 2JZ-GE (Non-Turbo) engine is manufactured with a large 8AN ORB internal bore supporting all horsepower 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 four 8AN ORB ports and is compatible with all fuel types including popular alcohol mixtures such as E85.

IMPORTANT: The fuel rail re-uses the factory mounting bolts and plastic spacers. Make sure these are present before beginning installation.

INFORMATION REGARDING OEM FUEL PRESSURE REGULATOR
Late model 2JZ-GE vehicles use a returnless fuel system where the fuel pressure regulator (FPR) is integrated into the pump assembly. However, early model 2JZ-GE vehicles use a traditional fuel system with the FPR mounted directly to the fuel rail. For these setups, an aftermarket pressure regulator will be required.

AFTERMARKET INJECTORS ON 2JZ-GE ENGINES WITH AIR-ASSIST
Late model (and California-spec) 2JZ-GE engines use Toyota air-assist emissions equipment. These engines use a unique OEM fuel injector that is not replicated in the aftermarket. Air-assist intake manifolds require the Radium injector seats in order to use universal aftermarket fuel injectors, as shown in the picture below. When the provided Radium injector seats are installed into these air-assist intake manifolds, an aftermarket injector that is 60mm long with 11mm upper O-ring and 14mm lower O-ring must be used. The following universal injectors have been verified to be compatible, however there are others on the market that will work that are not listed here.
Injector Dynamics ID1050-XDS-60-11-14
Injector Dynamics ID1300-XDS-60-11-14
Injector Dynamics ID1700-XDS-60-11-14
Injector Dynamics ID2600-XDS-60-11-14

FUEL RAIL PLUMBING, TOYOTA 2JZ-GE, RETURNLESS 
The fuel rail plumbing kit permits a complete fuel rail bolt-on affair. The provided inverted flare adapter fitting converts the factory hard line to 6AN. The included 6AN PTFE fuel line routes fuel to the rear fuel rail port through a low profile swivel fitting. A fuel pulse damper is provided to keep fuel pressure stable. The remaining fuel rail ports are plugged.
