Radium Secondary Top Feed Conversion Mazda RX-7 (FD3S)13B-REW

Special Note: Requires ACV Block off plate for fitment.

Radium Engineering secondary fuel rail kit is compatible with the 13B-REW 92-02 Mazda RX7 FD3S

The fuel rail has three ports that are tapped for 8AN ORB.

Appropriate fittings must be selected based on the specific application. 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. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

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.

PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB fittings. The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor using part number 14-0421, a pressure transducer, Radium fuel pulse damper, etc.
