Application: Toyota GR Yaris (2021+) and GR Corolla (2023+) – G16E-GTS
Part Type: Upgrade fuel rail
Part Number: 20-0766

The Radium 20-0766 is an anodised aluminium upgrade fuel rail for the Toyota G16E-GTS three-cylinder in the GR Yaris and GR Corolla. Its 0.6" internal bore supports the engine's power requirements, and the rail can be converted to a pressure-regulated return fuel system – ideal for custom fuel system builds.

The two end ports are 8AN ORB, while the two top ports are 6AN ORB to suit the narrow upper engine area. It installs without special tools and fits under the factory engine cover. For a plug-and-play connection to the factory fuel system, add the 20-0766-PK plumbing kit.
