Radium Engineering Fuel Rail Top Feed Conversion Mazda 20B-REW Primary - 20-0464

Fitment Information

  • Mazda 20B-REW Secondary

Specifications

Ports and Fittings

  • The fuel rail ports 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.

Product Description

The Radium Engineering high flow primary fuel rail is for the 20B-REW rotary engine originally found in the 1990-1995 Mazda/Eunos Cosmo. 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.

The three 8AN ORB ports are compatible with these fittings HERE. The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421 shown below), a pressure transducer, Radium fuel pulse damper, etc.

Insulating phenolic spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. The included 14mm lower injector seats were designed specifically to be compatible with or without the OEM diffusers in place. They feature Viton O-rings making them suitable for boosted applications.
