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
20-0361 Fuel Rails GM LS7
Manufactured with a large 0.69' internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. All end ports are machined with 8AN ORB (3/4-16 female) threads. The lower center ports can be used for optional adapters and are also tapped with 8AN ORB (3/4-16 female) threads. For a list of 8AN ORB adapter fittings, go HERE.
The kit features polished stainless steel mounts permitting the factory hardware.
The fuel rail ports are 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.

In comparison, the OEM GM LS7 uses an extra wide intake manifold. For fuel rail plumbing, our 20-0232-PK designed for the other LS platforms can be used along with a combination of our Inline 6AN to 1/8NPT adapter and a fuel pressure gauge to compensate for the extra width of the LS7 intake manifold. To order all 3 pieces needed, check all of the boxes in the plumbing kit selection above to add the parts that are needed to the cart.
