PORTS AND FITTINGS
The fuel rail ports are tapped for 8AN ORB.
Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
Mazda MZR (DOHC Inline-4)
Ford Duratec (DOHC Inline-4)
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’.
