Radium Fuel Pump Hanger - Nissan GT-R R35
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, while the return port is -8AN ORB female threaded. The system is compatible with alternative fuels such as methanol, ethaNol, E85, etc. Radium Engineering recommends reviewing the installation instructions before purchasing. 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: 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 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 that allows fuel in, but not out. The 1-way fill valves flow 355LPH each (1,065LPH total). All of the components work together to keep the collector box filled with fuel and prevent fuel pump starvation. PLUMBING: 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 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 20-0551-0X Fuel Hanger Feed Kits below). ELECTRICAL: 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. See the general recommendations 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. The installer must provide their own fuel pumps and perform final assembly. 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. 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. 20-0572 FEATURES: Drop-In OEM Replacement Permits 1, 2, or 3 Pumps Fuel Starvation Protection Integrated 1-Way Fill Valve (x3) High Current Electrical Hardware Compatible with Various Pumps Anodized Aluminum Construction 10AN ORB Threaded Outlet Port 8AN ORB Threaded Return Port 6-Hole Fuel Return Diverter Anodized Aluminum Collector Box Fuel Resistant Tubing and Wiring OEM Hard Line Compatible Stainless Steel Hardware Gasoline, Methanol, and Ethanol Compliant
