Radium - Fuel Rails for FR-S/BRZ/GT86/GR86

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). 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. This kit includes fuel rails and mounting brackets. Fittings and adapters sold separately. This option is ideal for users wanting to do their own custom lines and plumbing.

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 plumbing kit includes the items shown in the image below and allows easy hookup to the factory feed line. Has all the parts needed to complete the fuel rail installation. The PTFE hoses are resistant to all fuel types.

For early models, the ECU mount prevents the need to cut the OEM steel ECU mount and permits easy access to the RH fuel rail.

This is not compatible with the 2022+ BRZ and GR86.
