If you're looking to upgrade your Mazda RX-7's fuel system, the Radium Engineering Fuel Rail Top Feed Conversion is a fantastic choice. Designed specifically for the 1992-2002 RX-7, this aluminum fuel rail is anodized black, making it compatible with all popular fuel types, including E85. You can trust that it's built to handle your engine's power requirements with ease, thanks to its large internal bore.
This fuel rail features three 8AN ORB ports that are perfect for various fittings. The extra center port is a thoughtful addition, allowing you to connect additional fuel system accessories. Whether you want to incorporate the OEM fuel temperature sensor (using part number 14-0421), a pressure transducer, or a Radium fuel pulse damper, you have the flexibility to customize your setup.
To keep your fuel at the optimal temperature, we've included insulating phenolic spacers and washers along with stainless steel hardware. These components work together to prevent thermal energy from transferring heat into your fuel, ensuring that your system operates efficiently.
The included 14mm lower injector seats are designed with versatility in mind. They work seamlessly with or without the OEM diffusers, and they are equipped with FKM O-rings, making them ideal for boosted applications. You can feel confident that these seats will support your performance goals.
