    Honda B-Series Fuel Rail by Radium Engineering

    The rail features a large 0.69" internal diameter bore to suit even the most fuel hungry engines. They are CNC machined from 6061 aluminum, anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors, or any equivalent aftermarket injector, can be used. Three ports are machined with 8AN ORB (3/4-16 female) threads.

    There is a provision to reuse the OEM fuel pressure regulator (FPR). If not using the OEM FPR, there will be an open 1/8NPT port that can be used for ancillary sensors, or it can be plugged.

    The kit is compatible with all fuel types including popular alcohol mixtures such as E85. The fuel rail mounts using the OEM studs, nuts, and insulating spacers.

    The OEM Configuration kit makes this a bolt-on plug and play replacement for the factory fuel rail. It is designed to be used with the OEM fuel pressure regulator and fuel pulse damper. The kit includes -6AN vapor shield hose to replace the factory feed hose from the filter to the rail. This is a good option for a quick plug-and-play installation.

    Great option for JDM B18C

    Quality of the rail and AN fittings are top notch - wouldn't expect anything less from Radium. Professional parts with professional fit and finish. MAPPerformance had the best price and great, quick customer service answering questions via phone. Couldn't be happier. If I had to offer a constructive recommendation for how to make the Radium rail perfect aesthetically, it would be to provide screw-in plugs to fill the unused screw holes where the OEM FPR mounts when utilizing an aftermarket setup.
