Manufactured with 0.6" large internal bores, the Radium Engineering fuel rails can support all necessary engine power requirements. The 2 end ports are 3/4"-16 threaded (8AN ORB). The upper area of the engine is very narrow so the 2 top ports are 9/16"-18 threaded (6AN ORB)

Stainless steel mounting tabs (shown) are included for superior strength. 

The OEM fuel injectors are compatible with these fuel rails. The machined ports are compatible with 11mm upper injector O-rings, as shown below. Because of the tight clearance, the injector electrical connector can be tricky for aftermarket injectors.

When used in conjunction witht he 20-0766 fuel rail, the 20-0766-PK add-on plumbing kit permits a plug and play connection to the factory G16E-GTS fuel system.
