Fuel Rail, Mazda 13B-RE Secondary

The Radium Engineering high flow secondary fuel rail is for the 13B-RE 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. Like the stock fuel rail, the rail features 11mm injector bores permitting the use of OEM fuel injectors (shown below).

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 (shown above), etc.
