Radium: Fuel Rails, GM Vortec 8100 L18 Big Block
The fuel rails are CNC machined from 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Each fuel rail has six 8AN ORB ports, twelve ports in all.
There are 6 ports on each fuel rail (12 total). These ports are 3/4"-16 tapped for 8AN ORB fittings.
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.
