Radium Engineering S13 SR20DET Fuel Rail

The Radium SR20DET S13 fuel rail has a 0.69" (17.5mm) bore that is CNC machined from billet aluminum.

This fuel rail was designed to work seamlessly with injectors from Injector Dynamics, although other brands with the same injector height will work.

The S13 SR20DET fuel rail mounts to the factory bosses using 3 unique stainless steel brackets for a quick bolt-on installation. This fuel rail also fits the popular GReddy intake manifold without modification.

There are four customizable ports on the fuel rail for flexibility in plumbing of the fuel system. The front port is a 3/4-16 (-8AN) O-ring thread. Radium offers a variety of different screw-in adapters for this port (-6AN, -8AN, -10AN). The rear port is 3/8NPT that can accommodate an adapter fitting for -6AN hose or a fuel pulse damper. Also available for the rear port is a special adapter (sold separately) that allows installation of the OEM Nissan fuel pressure regulator.

These fuel rails are intended to be used in competitive racing applications ONLY; customer assumes all risk for complying to federal and state emissions laws.
