Radium Fuel Rail Kit — Subaru BRZ / Toyota 86 / GR86 (2012-2021 & 2022+)
These Radium Engineering fuel rails feature a large 0.69" internal bore capable of supporting all necessary engine power requirements across the full range of BRZ and 86 builds. The left and right rails are identical, featuring anodized aluminium bodies and mounting brackets. End ports are tapped for 8AN ORB and the centre port is tapped for 6AN ORB — providing maximum flexibility for fuel system plumbing.
Note: This listing includes fuel rails and mounting brackets only. Fittings and adapters are sold separately. For a complete plumbing kit, see 20-0111-PK. This option is ideal for custom fuel system builds where specific fittings and line routing are required.
Ensure ample clearance around the fuel rail port(s) for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. Dimensional drawings are available on the product page for reference.
Vehicle Fitment:
- Subaru BRZ ZC6 (2012-2021)
- Subaru BRZ ZD8 (2022+)
- Toyota 86 ZN6 (2012-2021)
- Toyota GR86 ZN8 (2022+)
Fitment Note — 2012-2021 BRZ and 86: Consider purchasing the Radium 20-0353 ECU Mount as a complement. This prevents the need to cut the OEM steel ECU mount and permits easy access to the RH fuel rail. Not compatible with the 2022+ BRZ and GR86.
