OVERVIEW

This high volume fuel rail works on all 2ZZ-GE and 1ZZ-FE engines. Both ends of the rail are tapped to 8AN ORB female threads. These ports use positive O-ring seals instead of tapered pipe threads which commonly damage aluminum threads and lead to fuel leaks.

The center port accommodates the OEM fuel pulse damper (not included) from the factory fuel rail. This helps alleviate all high frequency pressure fluctuations.

FUEL INJECTOR COMPATIBILITY

This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. This means that the injectors being installed must match the OEM height and o-ring dimensions. Radium Engineering cannot specify any further injector dimensions other than stating "OEM equivalent".

PORTS AND FITTINGS

The end ports of this fuel rail are tapped for 8AN ORB. A center port for the factory fuel pulse damper is also included.

8AN ORB Adapter Fittings can be found HERE
8AN ORB Direct Mount Regulators 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.
