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).


12-21 Toyota GT86
2022+ Toyota GR86
2012+ Subaru BRZ
12-16 Scion FR-S

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 fuel rail is compatible with factory or OEM equivalent fuel injectors.

If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.


20-0111-02 Fuel Rail, FR-S/BRZ/GT86/GR86
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.

20-0111-PK Fuel Rail Plumbing, FR-S/BRZ/GT86/GR86
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 2012-2020 BRZ, FR-S, and GT86 ONLY
As a compliment, consider purchasing 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.
