Radium Bränslearmatur Supra Jza80 OLD

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
Walbro F90000274
Walbro GSS342 255lph

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 handles 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. Nylon 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.

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.

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.
