Radium Engineering Fuel Hanger Nissan R35 GT-R - Pumps Not Included

Radium Engineering fuel hanger completely replaces the factory in-tank fuel pump unit in the R35 GTR 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, while the return port is -8AN ORB female threaded. The system is compatible with alternative fuels such as methanol, ethnaol, E85, etc

PREVENTING FUEL STARVATION
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.
NOTES:
1. Depending on fuel pressure, the venturi jet pumps will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
2. 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.



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).

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 20-0551-0X Fuel Hanger Feed Kits below).

FUEL PUMPS
The 20-0572 fuel pump hanger is compatible with both brushed and brushless fuel pumps. Any combination of 1, 2, or 3 pumps can be configured.

Traditional Brushed Fuel Pump Compatibility
Designed specifically for the AEM 50-1200 and Walbro GSS342 (255lph) fuel pumps. However, there are many other make/model of pumps that fit this same fitment and electrical connection that can potentionally work as well. CLICK HERE for information on fuel pumps carried .
NOTE: The larger Walbro DCSS 39/50 E85 pumps (F90000267/274/285/295) are not physically compatible with this product.

Brushless Fuel Pump Compatibility
For vehicles with high fuel demands, a brushless fuel pump system may be a good option. This Radium in-tank hanger system is compatible with up to three Ti Automotive E5LM brushless fuel pumps. Check valves are supplied so that multiple Ti Automotive E5LM pumps can be used without back-flow between pumps.
NOTE: A brushless fuel pump requires a separate stand-alone controller.
