Radium Fuel Rail Kit - FR-S / BRZ / 86


This 0.69" ID big bore fuel rail kit is designed for the FA20 engine found in the 2013+ Subaru BRZ and Scion FR-S. 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.
