Primary and Secondary Fuel rails Primary rail requires 34mm x 14 x 14 injectors. The opening and closing of the injectors creates. For the Xcessive Manufacturing 4-port intake manifold, the included 11mm phenolic spacers will be used. Includes 8AN ORB plug & 8AN ORB fittings( to 6an) for use with 6an hoses. The Radium fuel rail is the first and only on the market to support an (optional) fuel pulsation damper. With this fuel rail, all lower intake manifolds variations are compatible with the fuel injectors listed below. 20-0158, radium engineering, radium sr20det fuel rail, radium dmr, radium fuel pressure regulator, fic injectors, fic sr20det injectors, fuel injector. They feature Viton O-rings making them suitable for boosted applications. Both ports use positive o-ring seals instead of tapered pipe threads. Both ends of the rail are tapped to a common 3/4-16 (-8AN) female thread. This all new design was specifically designed to clear the intercooler mounting boss. The included 14mm lower injector seats were designed specifically to be compatible with or without the OEM diffusers in place. Product Details Features Warranty Reviews (0) Fuel Rail Kit by Radium. Also, for the required space, an air control valve delete for the OEM 13B-REW intake manifold (sold separately) is required. The two M8 extension mounts are made from stainless steel for superior strength and corrosion resistance.įor the OEM 2-port intake manifold, the included 20mm phenolic spacers, billet injector seats, and 2AN ORB plugs will be used. Insulating phenolic spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. 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. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements. 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 Radium fuel rail converts the OEM side feed fuel injector setup to top feed injectors, allowing the use of a wide variety of aftermarket fuel injectors. This Radium Engineering secondary fuel rail is for the Mazda 13B-REW rotary engine. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide. 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.
