13B Rotary Top Feed Fuel Rail Conversion Kit by Radium

The Radium Engineering high flow primary fuel rail is for the 13B-RE and 13B-REW rotary engine found in the 1990-1995 Mazda/Eunos Cosmo and 1992-2002 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. Like the stock fuel rail, the rail features 11mm injector bores permitting the use of OEM fuel injectors.

The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor, a pressure transducer, a 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.
