Description

The Radium Engineering fuel rails are manufactured with dual 3/8" (6AN) internal bores that internally connect to all injectors. Combined, these dual bores are 12% larger than a single 1/2" (8AN) bore. This system can support all necessary engine power requirements and is compatible with all alternative fuels.

The O-ring sealed billet end cap ports are 3/4"-16 thread tapped compatible with 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.

 

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.
