Radium Engineering Fuel Rails, FR-S/BRZ/86

PORTS AND FITTINGS

The fuel rail end ports are tapped for 8AN ORB and the center port is tapped for 6AN ORB.

6AN ORB Adapter Fittings can be found HERE.
8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators 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.

The Radium Engineering fuel rails are designed for the engine found in the Subaru BRZ (FA20D), Scion FR-S (FU-GSE), and Toyota 86 (4U-GSE).
