Fuel Rails for GM LS1 / LS2 / LS3 / LS6 / L76 / L99 Radium Engineering

PORTS AND CONNECTIONS

The fuel rail ports are 8AN ORB thread.

8AN ORB Adapters, 8AN ORB Direct Mount Regulators, 8AN ORB Fuel Pulse Dampers, Fuel Pressure Gauge Adapters

Appropriate connections must be selected for the specific application. Sufficient space around the fuel rail ports for larger accessories, such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers, needs to be taken into consideration. For clearance verification, dimensional drawings can be viewed on the product pages.
Manufactured with a generous 0.69" internal bore, the fuel rails can support all engine power requirements. They are CNC machined from 6063 extruded aluminum, black anodized, and laser engraved for a high-quality surface finish. All end ports are machined with 8AN ORB (3/4-16 female) threads. The bottom center ports can be used for optional adaptors and are also threaded with 8AN ORB (3/4-16 female) threads.
