These kits are compatible with 1 or 2 fuel pumps. Consult the installation instructions link at the top of this page for more details. The internal pump bracket permits mounting for the temperature sensor. The collector box permits mounting for level as shown above. The factory fuel temperature and level sensors are re-used. All necessary electrical hardware is provided for external wiring connections. Nonconductive anodized acorn nuts are provided to prevent any accidental short circuits. The low profile design keeps all wiring tucked nicely underneath the OEM access cover. Each pump has it's own dedicated +/- electrical connections. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Unlike compact multi-pin electrical connectors, these custom designed stainless steel electrical studs easily handle the high current demand from aftermarket fuel pumps. Select qty1 for single pump applications and qty2 for dual pump applications. Fuel pump wiring kits can be purchased HERE.
#Radium fuel pump hangers upgrade
However, it is recommended to upgrade the OEM wiring to get the maximum potential out of these high current, high flow pumps. Single pump applications can reuse the OEM fuel pump controller wiring, as shown below. NOTE: a post pump fuel filter is still required. External fuel line merging is no longer required. Each fuel pump merges internally into a single port. This port is thread tapped for 6AN ORB (9/16"-18). A SAE quick connect male adapter fitting is preinstalled for connecting to the OEM crossover line.Īn external fuel hanger plumbing kit is no longer required if the factory fuel lines are reused (as shown above).
This port is thread tapped for 6AN ORB (9/16"-18). A SAE quick connect male adapter fitting is preinstalled for connecting to the OEM return line. A SAE quick connect male adapter fitting is preinstalled for connecting to the OEM feed line. This port is thread tapped for 8AN ORB (3/4"-16). The duckbill valve prevents back flow and reduces fuel spray noise.Īs described below, there are 3 external ports: 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.įurthermore, 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 included a venturi jet pump features an integrated PRV (pressure relief valve). Each fill valve flows 355LPH (710LPH total). Furthermore, there are two 1-way fill valves on the collector box thats allow fuel in but not out. To help prevent starvation, the anodized aluminum collector box keeps fuel trapped around the pumps. No permanent modifications are required making installation simple. The machined assembly mounts in the factory fuel tank using the OEM gasket and replaces the OEM hold-down flange. The system is safe to use with alternative fuels such as E85. 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 fuel pressure regulator that is normally inside the OEM fuel unit is discarded. To adapt the OEM fuel level sensor to the Radium fuel pump hanger, 20-0850 FUEL LEVEL SENDER ADAPTER, FA20 is required.Ģ. The OEM fuel tanks may be the same, but the OEM fuel units are completely different. The 2 vehicles listed above require extra components described below.ġ.
