Full Description:
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.

To simplify 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.

High Speed Cruising

As shown, the sub-tank stays full in all driving conditions.

High Speed Turning

A bespoke stainless steel triple pump mesh strainer is included for proper fuel pump inlet filtration.

Bespoke Stainless Steel Triple Pump Mesh Strainer

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 Kit (not included.)
