Early Subaru/Saab Fuel Pump Hanger by Radium Engineering

The Radium fuel pump hanger allows the use of 1 or 2 aftermarket high-flow fuel pumps.

The machined assembly mounts in the factory fuel tank using the OEM gasket and hardware. The fuel level sender and temperature sensors are retained. The pumps merge into a single port outlet with 8AN ORB threads. The crossover and return uses 6AN ORB threaded ports. To simplify plumbing, the kit includes OEM hose adapter fittings for all model years listed. -6AN male fittings are included for those that use aftermarket feed and return hoses.

The custom designed stainless electrical studs easily handle the high current demand that compact bulkhead connectors lack. These serviceable connections are properly sealed and impervious to all standard and exotic fuels. The low profile design keeps all wiring tucked nicely underneath the OEM cover plate. Nonconductive acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE. Stainless steel crimp-on ring terminals and heat shrink are provided for external wiring connections.

There is a 1" check valve incorporated on the front side of the tank that serves as a trap door keeping the pump(s) supplied with fuel during aggressive driving. Furthermore, all returning fuel from the pressure regulator return and the crossover hose enter the collector box keeping it full. The OEM fuel level and fuel temperature sensors secure to the mounting bracket.

Please Note:

  • Single pump applications can reuse the OEM fuel pump controller, but it is recommended to upgrade the wiring as high flow fuel pumps draw additional current requiring larger gauge wire.
  • If supplying your own pumps, select the option "No Pumps Included" from the menu. There will be enough components included with this option to use 1 or 2 fuel pumps. Depending on the setup, some parts will simply not be used.
