Radium Engineering Fuel Rail | Honda B-Series

Upgrade your fuel system with the Radium Engineering Fuel Rail designed for Honda B-series engines. Built to support everything from mild builds to high-horsepower setups, this fuel rail features a large internal bore to ensure consistent fuel delivery under increased demand.

CNC machined from 6061 aluminum, each rail is finished with a durable black anodized coating and laser-etched for a clean, high-quality appearance. Designed with 11mm injector bores, it is fully compatible with factory injectors as well as OEM-style aftermarket options, making it a versatile upgrade for a wide range of builds.

The rail is designed to reuse the factory fuel pressure regulator (FPR), while also offering additional ports for expanded functionality. If not using the OEM regulator, the integrated 1/8 NPT port can be used for sensors or plugged. It is also compatible with Radium’s 8AN ORB fuel pressure regulators and fuel pulse dampers for more advanced setups.
