Description
20-0780-00, 20-0781-00 & 20-0782-00 Late Subaru Fuel Hangers
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.
PREVENTING STARVATION
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 that will 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.
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.
PLUMBING
- FUEL PUMP OUT: This port is thread tapped for 8AN ORB (3/4"-16). An SAE quick connect male adapter fitting is preinstalled for connecting to the OEM feed line.
- FPR RETURN: This port is thread tapped for 6AN ORB (9/16"-18). An SAE quick connect male adapter fitting is preinstalled for connecting to the OEM return line.
- CROSSOVER: This port is thread tapped for 6AN ORB (9/16"-18). An SAE quick connect male adapter fitting is preinstalled for connecting to the OEM crossover line.
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.
ELECTRICAL
Single pump applications can reuse the OEM fuel pump controller wiring. 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 anti-rotation 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. Anti-rotation electrical terminals are now featured as well. Nonconductive anodized acorn nuts are provided to prevent any accidental short circuits. All necessary electrical hardware is provided for external wiring connections.
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. Consult the installation instructions link at the top of this page for more details.

20-0850 Fuel Level Sender Adapter FA20
The Subaru FA20F vehicles use a returnless fuel system. And because the OEM fuel unit is different, the fuel level float is unique as well. This kit provides the proper fuel level mount for the OEM sensor. It also includes a plate to block-off the unused holes on the collector box, as shown below. Select this option if installing into a Subaru FA20F engine vehicle.
