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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe 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.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eHOW THE FHST WORKS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe OEM fuel module contains the pump, fuel pressure regulator, filter and has 2 venturi jet pumps that supply fuel from both sides of the tank. However, the OEM fuel module still suffers from slosh resulting in an interruption of the engine's fuel supply. \u003cbr\u003e\u003cbr\u003eThe Radium FHST is the best solution in preventing fuel starvation. It installs in the opposite side of the fuel tank from the OEM fuel module and works together to keep fuel delivery consistent in all conditions. The OEM fuel module receives an upgraded fuel pump which is used to send fuel to the Radium FHST keeping the collector box filled. The OEM venturi jet pumps will still function as designed scavenging fuel from the bottom of the tank. The FHST pump(s) are used to supply fuel to the engine through an integrated fuel pressure regulator. As described below, the FHST pump(s) are supplied with fuel from 3 different sources: the pump in the OEM fuel module, the integrated fuel pressure regulator return, and 355LPH one-way fill valves on the bottom of the collector box that allows fuel in, but not out.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNOTES:\u003c\/strong\u003e \u003c\/span\u003e\u003cbr\u003e1. The OEM venturi system must be used with the Radium FHST. \u003cbr\u003e2. The OEM fuel module must be upgraded to a pump with at least 340LPH (@ 40psi) rated flow in order for the venturi system to work correctly.\u003cbr\u003e3.

Like the OEM setup, a fuel pressure regulator (FPR) is integrated into the Radium FHST. The difference is the regulator is externally mounted with an adjustment screw and a vacuum port. If an intake manifold vacuum hose is connected, the FHST's built-in fuel pressure regulator will operate at a 1:1 ratio permitting fuel pressure to proportionally increase with manifold (boost) pressure. Conversely, the vacuum port can remain open to atmosphere and pressure will remain constant (like OEM).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe returning low pressure fuel from the FPR is sent back into the FST collector box keeping it full. Also, 2 fuel return orifices are included for fine-tuning the desired fuel pressure to the fuel pumps' flow rate and potential hose plumbing restrictions.
