The 2 vehicles listed above require extra components described below. 

1. The OEM fuel tanks may be the same, but the OEM fuel units are completely different. To adapt the OEM fuel level sensor to the Radium fuel pump hanger, 20-0850 FUEL LEVEL SENDER ADAPTER, FA20 is required.
2. The OEM fuel system is returnless. The fuel pressure regulator that is normally inside the OEM fuel unit is discarded. An aftermarket FPR is required.

 

The Radium fuel pump hanger for late model Subaru vehicles replaces the OEM unit and allows the use of 1 or 2 high-flow aftermarket fuel pumps. The system is safe to use with alternative fuels such as E85. The machined assembly mounts in the factory fuel tank using the OEM gasket and replaces the OEM hold-down flange. No permanent modifications are required making installation simple. To help prevent starvation, the anodized aluminum collector box keeps fuel trapped around the pumps. Furthermore, there are two 1-way fill valves on the collector box thats allow fuel in but not out. Each fill valve flows 355LPH (710LPH total). The included a venturi jet pump features an integrated PRV (pressure relief valve). This transfers fuel from the passive side of the OEM fuel tank to the active side where the pump(s) reside. This unique design creates suction without restricting the return line. Furthermore, all returning fuel from the FPR 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 fuel spray noise.

An external fuel hanger plumbing kit is no longer required if the factory fuel lines are reused. Each fuel pump merges internally into a single port. External fuel line merging is no longer required.

NOTE: THE FUEL HANGER ELIMINATES THE POST PUMP FILTER. A LOW MICRON FUEL FILTER WILL NEED TO BE INSTALLED DOWNSTREAM. THE FUEL PLUMBING KITS BELOW INCLUDE THIS REQUIRED ITEM.

Single pump applications can reuse the OEM fuel pump controller wiring, as shown below. However, it is recommended to upgrade the OEM wiring to get the maximum potential out of these high current, high flow pumps. Unlike compact multi-pin electrical connectors, these custom designed stainless steel electrical studs easily handle the high current demand from aftermarket fuel pumps. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. The low profile design keeps all wiring tucked nicely underneath the OEM access cover. Each pump has it’s own dedicated +/- electrical connections. Nonconductive anodized acorn nuts are provided to prevent any accidental short circuits. All necessary electrical hardware is provided for external wiring connections.

NOTE: FUEL PUMP WIRING KITS SOLD SEPARATE.

The factory fuel temperature and level sensors are re-used. The collector box permits mounting for level as shown above. The internal pump bracket permits mounting for the temperature sensor.
