OVERVIEW

Manufactured with 0.7" large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements.

FUEL INJECTOR COMPATIBILITY

The machined injector ports are compatible with 11mm upper injector O-rings.
The fuel rails are compatible with OEM fuel injectors (or equivalent). This means that the injectors being installed must match the OEM height and o-ring dimensions. Radium can not make fuel injector recommendations other than stating "OEM equivalent".

PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB. Each fuel rail has three 8AN ORB (3/4"-16) ports. 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.
