Radium Engineering Fuel Hanger Feed – Mazda RX7 FD

This Radium Engineering feed kit is designed specifically for the FD RX-7 and provides a high-performance fuel delivery solution using -8AN lines and premium filtration. The system is compatible with the Radium Fuel Pump Hanger or FHST and requires no cutting or drilling for installation.

A 1/2" Radium fuel hose connects the hanger outlet to a Radium high-flow fuel filter, which is securely mounted to the rear subframe using a custom FD-specific billet bracket. From the filter, a pre-assembled -8AN PTFE feed line routes cleanly along the chassis to the engine bay. A 45° hose end is provided at the termination point, allowing for flexible connection to a variety of aftermarket fuel systems.

This system ensures optimal fuel flow and reduced temperatures thanks to the integrated heat exchanger, making it ideal for high-powered rotary builds and ethanol-blend fuels.
