Overview

Radium Engineering Fuel Pump Hangers

Radium Engineering fuel pump hangers permit the use of one, two, or three aftermarket pumps in the stock MK4 Toyota Supra (JZA80) fuel tank.

Features include:

* Drop-in OEM replacement
* 8 AN male pump outlet
* 6 AN male return inlet
* Fuel starvation protection
* High current electrical hardware
* Compatible with various pumps (Walbro, AEM, etc.)
* Anodized aluminum construction

To simplifying aftermarket -AN hose plumbing, the 10 AN ORB threaded feed port features a low-profile 8 AN male fitting, and the 8 AN ORB threaded return port features a low-profile 6 AN male fitting. To reconnect the OEM return and vent hoses, 8.5mm barb fittings are also included. 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. 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 these kits, 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.
