The Radium fuel pump hanger permits the use of one or two Walbro E85 fuel pumps and is compatible with the following vehicles:
2012+ Toyota 86
2012+ Subaru BRZ
12-16 Scion FR-S
1. This system isonlycompatible with "Walbro 450" pumps (Ti Automotive F90000267 andF90000274).For more information on fuel pump identification, clickHERE.
2. This system requires the use of anaftermarket fuel pressure regulator.
3. This system eliminates the OEM hanger's "post" fuel pump filter. A low micronaftermarket fuel filtershould be installed downstream to protect the injectors from contaminants.
The machined assembly mounts in the factory fuel tank using the OEM ring and gaskets and reuses the OEM fuel level sender. A single -8AN male pump feed port and -6AN male return port simplify aftermarket -AN hose plumbing. The complete assembly fits under the OEM access cover without modification.
The custom designed stainless electrical studs easily handles the high current demand that compact bulkheadconnectors 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. Nylon acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE.
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 a FT86-specific contoured billet 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 are two 1" check valve balls incorporated on the tank that serves as trap doors keeping the pump(s) supplied dynamically 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. Theduckbill valveprevents back flow and reduces noise from fuel spray. The collector box also permits a mounting solution for the OE
