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. 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.

Fitment notes for 2012-2021 BRZ and 86:

As a compliment, consider purchasing part number 20-0353 Radium ECU Mount. This 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.

Injector Compatibility

This fuel rail is compatible with factory or OEM equivalent fuel injectors including Injector Dynamics. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.

Kit Includes:

  • Just 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.

For fittings and plumbing see kit part number 20-0111-PK
