Toyota MK4 Supra (JZA80)
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 GSS342 255lph
AEM 50-1200 E85
To 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 ETFE. 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.
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.
OPTIONAL FUEL HANGER PLUMBING KIT
These plumbing kits include everything required to plumb the fuel system between the Radium pump hanger and the fuel rail in the JZA80 Supra. This plumbing kit is designed to work best with a Radium Engineering fuel rail for the 2JZ (20-0215), but may also work with other aftermarket fuel rails. This kit IS NOT COMPATIBLE with the stock 2JZ fuel rail.
The kit includes a pre-made -8AN PTFE feed line that runs from the fuel pump hanger to the fuel filter. Then out of the fuel filter a pre-made -10AN is used to connect to the fuel rail inlet. The fuel lines clear the OEM fuel pump cover and do not require any cutting or drilling to get them past the fuel tank.
For the return line, -6AN E85 compatible rubber fuel hose runs from the pressure regulater bac k to the fuel pump hanger return port. The fuel lines run though these billet aluminum line retainers (green brackets) which are included. The return hose E85 compatible rubber and can be easily modified for installation of an in-line flex fuel sensor.
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 (-03,-05), the fuel filter will be assembled with a choice of different elements. Go HERE for more filter element information. The -05 version is most popular because it meets filtration requirements set forth by Bosch Motorsports and works well with E85.
