Add multiple options for inlet and outlet locations. Add return line. Tap a plug for a fuel rail pressure sensor! Soooo many options!

Fit's many 2001-present Ford Duratec 2.0 2.3 2.5 and Mazda MZR applications such as Focus, Ranger, Miata MX-5, Escape, Fusion, 3, 5, 6 etc. NOT for direct injected engines.

This Radium Engineering fuel rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish.


Like the original fuel rails, the injector bores are 14mm ID so factory injectors are permitted. Furthermore, provisions for the OEM injector retaining clips are implemented as well.


The rails are compatible with all fuel types including popular alcohol mixtures such as E85.


Spacers and washers are included to thermally insulate the fuel rail from the cylinder head.


FUEL INJECTOR COMPATIBILITY

This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.
