Radium Fuel Rail Kit, Toyota GR Yaris XPA16R / GR Corolla GZEA14R

The Radium Engineering 20-0766 Fuel Rail Kit is a billet aluminium fuel rail solution for the Toyota GR Yaris (XPA16R) and GR Corolla (GZEA14R), both powered by the G16E-GTS turbocharged three-cylinder engine. With a large 0.6" internal bore, this rail supports all engine power requirements without flow restriction — from stock builds through to high-power forced induction applications.

The OEM fuel injectors are compatible with these rails. Machined ports accept 11mm upper injector O-rings. Due to the tight clearance in the upper engine area, aftermarket injector electrical connectors may be difficult to fit — Bosch EV14 format injectors are confirmed compatible. The rail can also be converted to a pressure-regulated return fuel system for custom builds.

This kit includes the fuel rail and all necessary mounting hardware only — ideal for custom fuel system builds. For a plug-and-play OEM hookup, pair with the Radium 20-0766-PK Plumbing Kit.
