Description
The Radium Engineering Fuel Rail Plumbing Kit for 2023+ Toyota GR Corolla is engineered as a purpose-built solution for enthusiasts who want the surrounding system to be easier to package, service and trust under hard use.
Why This Upgrade Matters
A purpose-built plumbing kit removes much of the guesswork from converting a fuel rail installation into a complete working system. Correct hose routing, fittings and interfaces are especially valuable in tightly packaged engine bays where improvised plumbing can create serviceability, heat-management or clearance problems.
Product-Specific Details
When used in conjunction with the 20-0766 fuel rail, the 20-0766-PK add-on plumbing kit permits a plug and play connection to the factory G16E-GTS fuel system. A 6AN ORB fitting plugs the upper RH port and a 8AN ORB fitting plugs the RH side port. A 8AN ORB clamp assembly adapts the OEM fuel pressure sensor to the RH side port. The upper LH port features adapters to position the SAE quick conect fuel feed fitting in the proper locatio Note: Part #20-0766 fuel rail is sold separately and not included.
Fitment & Application

Technical Notes
Treat the plumbing kit as part of the complete fuel-system layout. Confirm whether the build remains returnless or is being converted to a return-style system, and account for the regulator, filter, sensor, damper and pump configuration before installation.

Enthusiast Notes
This is the kind of part that makes a finished engine bay look intentional: fewer improvised adapters, cleaner routing and a system that can be inspected quickly between sessions.
Before Ordering
Confirm the matching Radium rail/hanger part number and the intended fuel-system architecture. Pumps, injectors, filters and regulators may be separate depending on the kit.
