If you're looking to upgrade your Toyota Mk4 Supra (JZA80) fuel system, the Radium Engineering Fuel Pump Hanger is a fantastic choice. This innovative hanger allows you to install one, two, or even three aftermarket pumps in your stock fuel tank, all without needing to make any permanent modifications to the fuel access cover.
To make your life easier when it comes to plumbing, the hanger features a 10AN ORB threaded feed port with a low-profile 8AN male fitting. Plus, the 8AN ORB threaded return port comes with a sleek 6" male fitting. This thoughtful design simplifies the installation process, ensuring you can get back on the road in no time.
The fuel pumps are equipped with integrated check valves that merge the pump outlets into a single 10AN billet collector, ensuring optimal fuel flow. For those who want to reconnect the OEM return and vent hoses, we've included barb fittings to make the transition seamless.
Worried about high current demands? The custom-designed stainless electrical studs are here to save the day! Unlike standard bulkhead connectors, these studs are built to handle the high current without any issues. They're also properly sealed to withstand all types of fuel, both standard and exotic. The low-profile design keeps everything tucked neatly under your OEM fuel tank cover, thanks to the provided foam insulation.
To keep things safe, we've included nonconductive acorn nuts to prevent accidental short circuits. Our high-quality in-tank wiring is insulated with chemically resistant ETFE, ensuring durability. You'll also find all the necessary electrical hardware for the fuel pump(s), OEM level sender, and OEM temperature sensor. If you're using a single pump, you can easily reuse the OEM fuel pump controller wiring, but we recommend upgrading to larger gauge wire for those high-flow pumps. Fuel pump wiring kits are available for purchase; just select the quantity you need based on your pump setup.
One common issue with the older OEM system is fuel starvation. The Radium Engineering system addresses this with a unique siphon jet pump that uses a venturi effect to draw fuel from outside the sub-tank, directing it straight to the pump inlets. This innovative design ensures that the sub-tank remains full, no matter how you drive.
This fuel pump hanger is specifically designed for use with the following Walbro DCSS 39/50 fuel pump part numbers: F90000267, F90000274, and F90000285. To ensure proper fuel pump inlet filtration, we've included a custom stainless steel triple pump mesh strainer.
