OVERVIEW: The Radium Engineering Fuel Hanger Surge Tank (FHST) is the ultimate solution to fuel starvation issues in the Nissan Z33/V35 chassis. Due to the OEM saddlebag style fuel tank and insufficient baffling, fuel starvation is common when the vehicle is aggressively driven, such as on a road course. This leads to unstable fuel pressure and potential engine damage from running too lean. A standalone surge tank is an excellent device for eliminating fuel starvation issues. However, installing a standalone FST is difficult, especially in the 350Z, due to the open cabin design and lack of a firewall between the driver and the rear of the vehicle. For this reason, Radium Engineering opted to create a fully functional fuel surge tank WITHIN the OEM fuel tank. The Radium FHST can be used with one or two aftermarket fuel pumps and delivers 1:1 regulated fuel to the engine. No grinding, bending, or sheet metal modification to the vehicle is required. Furthermore, the system is compatible with alternative fuels such as E85.
Features: Simple Installation, Allows Use of One or Two Surge Pumps, Brushless Fuel Pump Compatibility, Integrated 1:1 Adjustable Fuel Pressure Regulator, Fuel Pressure Gauge, Fuel Starvation Protection, High Current Electrical Components, Compatible With Popular Fuel Pumps, Anodized Aluminum Construction, Compatible With Gasoline, Methanol, and Ethanol, Fuel Resistant Lines and Wiring, Stainless Steel Components.
PUMP COMPATIBILITY: The FHST offers both brushed and brushless fuel pump options. The system is compatible with but not limited to the following fuel pumps: Walbro GSS342AEM 20-1830 & E85 50-1200. INCLUDES: The complete kit includes all necessary parts for installation such as the gauge, external fuel hose, fittings, electrical fuse, relay, etc. Fuel pumps must be purchased separately.
