8AN ORB Direct Mount Regulators 
8AN ORB Fuel Pulse Dampers

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.

This large bore fuel rail features a large 0.69" diameter internal bore. It uses all 5 OEM mounting bosses. The fuel rail is machined, anodized, and laser etched for a high quality surface finish. 

It is compatible with all fuel types including popular alcohol mixtures such as E85. It is also designed to work with OEM fitment fuel injectors.

The factory fuel pressure regulator can be used or the port in that location can be used for a 1/8" NPT fuel pressure gauge, transducer, plug, etc. 

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. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.
