The Radium fuel pump hanger allows the use of 1 or 2 aftermarket pumps. It is a drop-in replacement for the following models:
08-14 Subaru Impreza (Incl. WRX and STi)
08-14 Subaru Forester (all)
05-09 Subaru Legacy (Incl. 2.5GT)
05-09 Subaru Outback (Incl. XT)
2015+ Subaru STi (EJ engine only)
The machined assembly mounts in the factory fuel tank using the OEM hold-down flange and gasket. The OEM fuel level sender and temperature sensor (if equipped) are retained. Four -6AN male fittings (2 pump outlets, 1 return, 1 crossover) simplify plumbing with aftermarket -AN hose.
Wire connections are done with specially designed stainless steel studs. All in-tank wiring is high quality PTFE insulated for use in gasoline and ethanol.
Stainless steel crimp-on ring terminals and heat shrink are provided for external wiring connections.
The kit includes Radium's own venturi jet pump with interchangeable orifices. Without a properly designed jet pump, fuel cannot be properly transferred from the passive side of the OEM saddle bag fuel tank to the active side where the pump(s) reside. When fuel pump flow is increased, the OEM jet pump becomes too restrictive creating unwanted backpressure in the FPR return line causing excessive fuel rail pressure.
The kit also includes an anodized aluminum collector box. This container is NOT a total solution to fuel starvation, but does improve the fuel supply around the pump(s) inlet. 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 through a one-way duckbill valve keeping it full. The duckbill valve prevents back flow and reduces noise from fuel spray. The collector box also permits a mounting solution for the OEM fuel level and fuel temperature sensors. This new revision simplifies installation and permits the hanger to be simply dropped into the tank in 1-piece.
Single pump applications can reuse the OEM fuel pump controller wiring, but it is recommended to upgrade the OEM wiring as high flow fuel pumps draw additional current requiring larger gauge wire. Fuel pump wiring kits can be purchased HERE. Select qty1 for single pump applications and qty2 for dual pump applications.

Configuration
This kit is available with or without fuel pumps included. If you are going to use your own pumps or source pumps elsewhere, select the option "Single / Dual Hanger, Pumps Not Included" from the drop down. Note that 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.
Next, select the type of pumps that will be used so the appropriate internal wiring connectors will be included in the kit. If pumps are needed, the kit will come preassembled and 65 micron sock filters will be installed on all fuel pumps. Note: This kit eliminates the OEM hanger's "post" fuel pump filter. A low micron aftermarket fuel filter should be installed downstream to protect the injectors from debris.
Plumbing Kits
The optional plumbing kits include fittings and hoses to make the fuel pump hanger a direct bolt-in OEM replacement for both single and dual pump configurations. These kits do NOT require any extra fuel hose plumbing.
