Radium Fuel Hanger | 2009-2022 Nissan GT-R (20-0572)

2009-2022 Nissan GT-R Fuel Hanger by Radium Engineering

The Radium Engineering fuel hanger completely replaces the factory in-tank fuel pump unit in the R35 GT-R and permits up to three 39mm diameter aftermarket pumps (brushed or brushless) to supply fuel to the engine. No permanent vehicle modifications are required for installation. The pumps are housed in an aluminum collector box that is kept full during operation. This ensures that fuel starvation does not occur, even during aggressive driving. The fuel pump outlet port is -10AN ORB female threaded and includes a 6AN male adapter, while the return port is -8AN ORB female threaded and includes a 6AN male adapter. The system is compatible with alternative fuels such as methanol, ethanol, E85, etc. Radium Engineering recommends reviewing the installation instructions (link above) before purchasing.

The GT-R saddle bag style fuel tank uses two OEM venturi jet pumps. They supply fuel from both sides of the tank to the OEM pump bucket and are driven by fuel returning from the regulator. When the fuel pumps are upgraded, these venturi jet pumps become a restriction in the return line, resulting in elevated fuel pressures and unreliable regulator performance. By reconfiguring the venturi jet pump plumbing, Radium Engineering has kept their functions without impacting the returning fuel from the regulator. This allows the pumps to be upgraded without fuel pressure concerns.

In addition to the venturi jet pumps scavenging fuel, the pressure regulator return also keeps the large collector box filled with fuel. Additionally, the Radium Engineering 20-0572 incorporates three 355LPH one-way fill valves integrated to the bottom of the collector box (shown below) that allows fuel in, but not out. The 1-way fill valves flow 355LPH each (1,065LPH total).

To clear the OEM fuel pump cover plate, the standard fuel hanger kit includes low profile swiveling adapters that convert to 6AN male, along with short 6AN PTFE hoses and adapters for easy connection to the OEM fuel piping. Other adapter fittings are available and are sold separately.

FILTRATION: Sock filters are provided for all 3 fuel pump inlets. Since the fuel hanger eliminates the non serviceable post pump filter, an aftermarket filter is required to be installed downstream (see 20-0851-0X Fuel Hanger Feed Kits below).

The Radium fuel pump hanger features custom designed stainless electrical studs that easily handle the high current demand that multi-pin bulkhead connectors lack. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Non conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. Electrical hardware is included for the fuel pump(s) and OEM sensors. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE. The factory temperature and fuel level sensors are reused.

The factory GT-R fuel pump hanger utilizes two fuel pumps. In some cases, two aftermarket pumps can use the OEM wiring. However, custom wiring will be necessary to control a third pump.

Fuel pump wiring is specific to which fuel pump(s) is used and which trigger strategy will be implemented.

Please Note: Depending on fuel pressure, the venturi jet pumps will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps. If it is important for fuel pressure to hold steady after the engine is shut down, install one of these CHECK VALVES somewhere in the fuel system.
