FHST for Nissan R32 GT-R Pumps not Included Walbro GSS342 AEM 50-1200 Radium Engineering - USA-RAD-20-0740-00 - COMPATIBILITY Nissan R32 Skyline GT-R OVERVIEW The Radium Engineering FHST (fuel hanger surge tank) is the ultimate solution for fuel starvation issues. Fuel pump starvation is common when a vehicle is driven aggressively. Unstable fuel pressure resulting in a lean fuel mixture can cause engine damage. A stand-alone surge tank is an excellent device for eliminating fuel starvation, but installation can be complex. The FHST is a fully functional fuel surge tank contained inside the OEM fuel tank. It can be configured with 1, 2, or 3 high pressure pumps to feed fuel to the engine and 1 lift pump to keep the surge tank full. This system can meet the fuel demands of any engine power level. Even with all of the extra fuel pumps, the FHST system is very straight forward and relatively simple to install. No grinding, bending, or modification of the vehicle is required. Furthermore, the system is compatible with all alternative fuels such as E85. FUEL SURGE TANK The surge tank system works by keeping fuel trapped around the pump (or pumps) that feed the engine. This ensures that fuel starvation will not occur and the supply of fuel to the engine will remain steady under all driving conditions.  PLUMBING The preinstalled barb fittings permit direct connections to the factory fuel hoses. No extra fuel plumbing is required. Additionally, 8AN (feed) and 6AN (return) adapter fittings are provided for connecting aftermarket -AN style hoses. The fitting ports are machined low enough to clear the unibody sheet metal.  This system supports the following fuel pumps (make sure the correct hanger version is selected to match the pumps used): 20-0740-00Walbro GSS342 255lph AEM 50-1200 E85 FEATURES -Drop-In Installation-Anodized Aluminum Construction-Merged 8AN ORB Female Pump-Out Port-8AN ORB Female Return Port-Permits up to 4 Pumps Total -Compatible with up to 3 Brushless E5LM Pumps-High Current Electrical Hardware-Stainless Steel Hardware and Clamps-Gasoline, Methanol, and E85 Compliant Instruction PDF
