This 0.69"" ID big bore fuel rail kit is designed for the FA20 engine found in the 2013+ Scion FR-S, Subaru BRZ and Toyota 86 variants. The left/right rails are identical and feature anodized aluminum bodies and powder coated aluminum mounting brackets. The end ports of the fuel rails are female threaded for -8AN O-ring (3/4-16 thread) fittings. Each rail also has a center port that is threaded for -6AN O-ring (9/16-18 thread). A variety of common adapters can be used in these ports to construct a custom high flow fuel delivery system.

Necessary parts are included to make this a direct bolt-on replacement for the stock rail. The kit includes billet aluminum adapters that allows the OEM fuel pulse dampers to be retained. Also included are two -6AN PTFE hoses which make this kit compatible with all fuel types including popular alcohol mixes, such as E85.

Minor modification which includes cutting of the metal ECU mount is required for installation. Please download and read the Installation Instructions (PDF).
