Radium Engineering Mazda MZR / Ford Duratec Fuel Rail - 20-0503-02

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. 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.

The fuel rail ports are tapped for 8AN ORB fittings.

• 8AN ORB Adapter Fittings can be found HERE
• 8AN ORB Direct Mount Regulators can be found HERE
• 8AN ORB Fuel Pulse Dampers can be found HERE
• Fuel Pressure Gauge Adapters can be found HERE

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.

This kit includes all of the necessary adapters making the 20-0503-02 fuel rail a direct OEM fuel rail replacement. NOTE: For early Duratec engines, see below.

COMPATIBILITY

• 05-09 Ford Focus
• 05-08 Ford Escape

This is compatible with early Ford models which had a Bosch fuel pressure sensor mounted to the OEM fuel rail. This sensor is not very common on Duratec/MZR engines. As shown, it adapts to the OEM fuel pressure sensor to 8AN ORB (3/4"-16) using the factory screws. The adapter can be mounted on any of the available fuel rail ports.
