Description
Radium Engineering fuel rail F/H-serie engines.
Click here to download installation instructions (PDF).
This rail is manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. 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.
Compatibility
Compatible for the following Honda engines H22A1, H22A4, H23A1, F20A, F20B, F22A1, F22A4, F22A6.
However, there are likely many other variations that are compatible. And even though the Radium Engineering fuel rail has 3 fuel rail mounts, it will work on many of the 2-bolt intake manifolds, as shown below.
The fuel rail is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM spacers are required for mounting the fuel rail.
Fuel Rail Plumbing
The plumbing kit includes the items shown in the image below and allows easy hookup to the factory feed line. It is intended to be used with the factory pressure regulator, but can also work with an aftermarket regulator.
Extra fittings, hoses and other fuel plumbing items will be needed to complete the installation. For that, choose the option including plumbing kit.
Please note: choose the preferred option in the drop-down menu (with or without plumbing kit).
