PORTS AND FITTINGS
The fuel rail end ports are tapped for 8AN ORB and the center port is tapped for 6AN ORB.
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 2013+ engine found in the Subaru BRZ (FA20D), Scion FR-S (FU-GSE), and Toyota 86 (4U-GSE). Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The left/right rails are identical and feature anodized aluminum bodies and mounting brackets.
