This Radium Engineering secondary fuel rail is for the Mazda 13B-REW rotary engine.

With the use of the provided 2AN ORB plugs, this adaptable design permits both the OEM 2-port intake manifold and aftermarket 4-port intake manifolds.

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

Insulating spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. The two M8 extension mounts are made from stainless steel for superior strength and corrosion resistance.

For the OEM 2-port intake manifold, the included 20mm insulating spacers, billet injector seats, and 2AN ORB plugs will be used. Also, for the required space, an air control valve delete for the OEM 13B-REW intake manifold (sold separately) is required. See Radium 20-0449 HERE.

The included 14mm lower injector seats were designed specifically to be compatible with or without the OEM diffusers in place. They feature FKM O-rings making them suitable for boosted applications. NOTE: if using an Elite Rotary Shop 4-port intake manifold.

With this fuel rail, all lower intake manifolds variations are compatible with the fuel injectors listed below. For the Xcessive Manufacturing 4-port intake manifold, the included 11mm insulating spacers will be used.

Cute but not hinged at arms
Color: Porcini Tortoise, Size: 52-17-140
They were cute. I didn’t like that they weren’t hinged. They were harder to open and close. I didn’t look for this feature before I purchased.

Mis lentes son muy cómodos, y me gustan como lucen, vienen sin medidas yo los adecué con mi Optometrista. Se aflojan con el tiempo, pero compré una pinza que ajusta los tornillos…realmente lucen como nuevos.
