The Radium Engineering fuel pump hanger permits the use of 1, 2, or 3 aftermarket pumps in the stock MK4 Toyota Supra (JZA80) fuel tank.
This system is compatible with the following fuel pumps:
Walbro F90000267 (not stocked by Radium Engineering)
Walbro F90000274
Walbro F90000285
Walbro GSS342 255lph
AEM 50-1200 E85To simplifying aftermarket -AN hose plumbing, the 10AN ORB threaded feed port features a low profile 8AN male fitting and the 8AN ORB threaded return port features a low profile 6AN male fitting. To reconnect the OEM return and vent hoses, 8.5mm barb fittings are also included. Furthermore, no permanent modification to the OEM fuel tank access cover is required.
The custom designed stainless electrical studs easily handle the high current demand that compact bulkhead connectors 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 fuel tank cover using the provided foam insulation. Nonconductive acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE. Electrical hardware is included for the fuel pump(s), OEM level sender, and OEM temperature sensor.
One issue with all Supra fuel pump hangers is the lack of fuel starvation protection. In this kit, the flow from the FPR return line powers a Radium jet pump. Using a venturi-effect, this "mechanical" pump draws fuel from outside the sub-tank and distributes it directly to the pump inlets.
As shown, the sub-tank stays full in all driving conditions.
A bespoke stainless steel triple pump mesh strainer is included for proper fuel pump inlet filtration.
Because all compatible fuel pumps utilize integrated check valves, the pump outlets merge into a single 10AN billet collector.
Single pump applications can reuse the OEM fuel pump controller wiring, but it is recommended to upgrade the OEM wiring as these 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, qty2 for dual pump applications, and qty3 for triple pump applications.

Pump Configuration Selection
If supplying your own pumps, select the option "Pumps Not Included" from the menu.
Notes:
1. When purchasing "No Pumps Included", the kit will come preassembled as shown above.
2. There will be enough components included with this option to use 1 or 2 or 3 fuel pumps. Depending on the setup, some parts will simply not be used.
3. Because this kit includes a bespoke fuel pump inlet screen, the sock filters that typically come standard with these types of pumps are not required.
OPTION
20-0415-0X FUEL HANGER PLUMBING KIT, MKIV SUPRA
The plumbing kits include everything required to plumb the fuel system. This includes pre-made -10AN and -8AN PTFE feed lines that run from the fuel pump hanger through the fuel filter to an aftermarket 8AN ORB fuel rail (not included). The fuel lines clear the OEM fuel pump cover and do not require any cutting or drilling to get them past the fuel tank.
A -6AN fuel hose runs from the FPR (not included) to the pump hanger return port. The fuel lines run though these billet aluminum fuel brake line retainers.
The included Radium Engineering fuel filter mounts underneath the vehicle using a specifically designed MKIV Supra (JZA80) bolt-on billet mount.
Depending on the kit selected (-01,-03,-05), the fuel filter will be assembled with 1 of 3 different elements. Go
HERE for more filter element information.
INCLUDES
-Fuel Filter (-01 Cellulose, -03 Stainless, or -05 Microglass)
-Black 10AN and 8AN Male Adapter Fittings (x2)
-Billet Aluminum 60mm Filter 2-Piece Clamp
-Aluminum MKIV Supra Billet FIlter Mount
-10AN PTFE Fuel Feed Line
-8AN PTFE Fuel Feed Line
-6AN Fuel Return Hose
-Fuel Brake Line Retainers
-Stainless Steel Hardware
NOTES: To complete the system as designed, it is recommended to use the
Radium 20-0215 Fuel Rail with a combination of
Radium 20-0176 FPD-R,
Radium 20-0386, and
Radium 14-0332 for the center port fittings. And to connect to the rear port, a
Radium 20-0223 DMR mates up perfectly with the included PTFE return hose.
