FUEL INJECTORS

There are two type of fuel rails made by Radium: upgrade rails and top feed conversion rails. Upgrade rails only upgrade the rail and the OEM fuel injectors can be reused. If an upgrade to the injectors is desired, they must be equivalent to the OEM injector, meaning they must be the same height and the upper & lower O-rings must match the OEM diameters and styles. Top feed conversion rails are used to convert a vehicle that has side feed (or sometimes air-assist) injectors over to a top feed injector.

This fuel rail is an upgrade rail. OEM or OEM equivalent injectors must be used.

Radium does not make fuel injector recommendations.

Consult your tuner for injector brand or flow rate recommendations.
Consult the injector manufacturer for a part number that has the correct dimensions.

OVERVIEW

20-0862 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.

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