Application: Mazda RX-7 FD3S with Radium Fuel Hanger Surge Tank (20-0950/0951/0952)
Part Type: Fuel hanger feed kit with filter, 8AN
Part Number: 20-0455-03, 20-0455-05
The Radium Fuel Hanger Feed kit plumbs the Radium FD RX-7 Fuel Hanger Surge Tank (FHST) to the engine bay using high-flow 8AN lines. A 1/2" hose runs from the hanger outlet to a Radium fuel filter mounted on the rear subframe, and a pre-made 8AN PTFE line then runs forward to the engine bay, where the installer adapts the 45-degree hose end to suit their fuel system.
The lines clear the OEM fuel pump cover and suspension components, with no cutting or drilling required to pass the tank. The filter is held in a bolt-on billet mount designed for the FD RX-7 and runs through a Radium heat exchanger to help lower fuel temperature.
