Radium Engineering Fuel Rails 20-1302
Manufactured with large 5/8" internal bores, the fuel rails can support all necessary engine power requirements. They are CNC machined from 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Each fuel rail has 3 (6 total) 8AN ORB threads. The physical profile features maximized clearance with the distributor, while supporting maximum flow. Because of this innovative design, the fuel injectors are installed in an exact perpendicular orientation with respect to the LIM injector seats, exactly like OEM. No spacers required. These fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.
The fuel rail ports are tapped for 8AN ORB and 1/8 NPT 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.
