Description
Radium Engineering high flow secondary fuel rail is for the 13B-REW rotary engine. The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85 With the use of the provided 2AN ORB plugs, this adaptable design permits both the OEM 2-port intake manifold (shown above) 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 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 (shown below), 2 extra injector seats are required which can be purchased HERE.
