OVERVIEW The Radium Engineering FHST (fuel hanger surge tank) is the ultimate solution for fuel starvation issues in the Nissan Z33/V35 chassis. Due to the saddle-bag style OEM fuel tank and insufficient baffling, fuel starvation is common when the vehicle is driven aggressively, such as on a track. This results in unstable fuel pressure and possible engine damage from running too lean. A stand-alone surge tank is an excellent device for eliminating fuel starvation issues. But installing a stand-alone FST is difficult specifically in the 350Z due to the open-cabin design, and lack of a firewall between the driver and the rear of the vehicle. So Radium Engineering chose to create a fully functional fuel surge tank INSIDE the OEM tank. The Radium FHST can be used with 1 or 2 aftermarket pumps and supplies 1: 1 regulated fuel to the engine. No grinding, bending, or modification of the vehicle's sheet metal is required. Furthermore, the system is compatible with alternative fuels such as E85.
