Fuel Rail Top Feed Conversion Radium Engineering for Mazda 13B Primary

COMPATIBILITY

• 90-95 Mazda/Eunos Cosmo 13B-RE
• 92-02 Mazda RX7 FD3S 13B-REW

FUEL INJECTORS

The o-rings must be 14mm and the height must be the short 34mm body height shown.

Many injector manufacturers will offer injectors in this height and o-ring style. Below are a few examples of the part numbers that would be used when ordering Injector Dynamics injectors.

• Injector Dynamics 1050-XDS 1050.34.14.14
• Injector Dynamics 1300-XDS 1300.34.14.14
• Injector Dynamics 1700-XDS 1700.34.14.14
• Injector Dynamics 2600-XDS 2600.34.14.14

Fuel Injectors are NOT included and must be purchased elsewhere.

The Radium Engineering high flow primary fuel rail is for the 13B-RE and 13B-REW rotary engine found in the 90-95 Mazda/Eunos Cosmo and 92-02 Mazda RX7 FD3S. The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements.

PORTS AND FITTINGS

The fuel rail has three ports that are tapped for 8AN ORB.

• 8AN ORB Adapter Fittings
• 8AN ORB Direct Mount Regulators
• 8AN ORB Fuel Pulse Dampers
• Fuel Pressure Gauge Adapters

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.

The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421), a pressure transducer, Radium fuel pulse damper etc.
