RADIUM Engineering 20-1821 Fuel Hanger Surge Tank Nissan 370Z Brushless E5LM

The RADIUM Engineering FHST (Fuel Hanger Surge Tank) is the ultimate solution for fuel starvation issues in the Nissan Z34 and RZ34 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, resulting in unstable fuel pressure and possible engine damage from running too lean.

RADIUM Engineering chose to create a fully functional fuel surge tank INSIDE the OEM tank, eliminating the need for a difficult stand-alone external surge tank installation. 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.

Key Features:

• Drop-in installation for 2009-2020 Nissan 370Z (RH or LH drive)
• Integrated 1:1 adjustable fuel pressure regulator with externally mounted adjustment screw and vacuum port that permits fuel pressure to proportionally increase with manifold boost pressure
• Compatible with alternative fuels such as E85
• Anodized aluminum construction with stainless steel hardware
• In-tank wiring insulated with high quality chemically resistant ETFE
• One relay, one fuse, and all associated wiring and hardware provided to install 1 surge tank pump
• Includes pressure gauge, external fuel hose, fittings, and electrical components

Brushless Ti Automotive E5LM Configuration:

This version (20-1821) is configured specifically for brushless fuel pumps, suited for the Ti Automotive BKS1001 (brushless) E5LM pump. Because the brushless E5LM pump does not have an integrated check valve, this kit contains two bolt-on check valves that allow two pumps to be staged and for fuel pressure to remain in the system after the pump(s) turn OFF. The kit comes partially assembled with enough components included to run one or two surge tank fuel pumps.

Important Notes:

• Fuel pumps NOT included - purchase separately based on your power requirements
• 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
• The RADIUM integrated regulator should be the only FPR in the fuel system
• OEM venturi system must remain functional and unmodified

The comprehensive kit includes all parts necessary to complete the installation. This fuel hanger surge tank works in conjunction with the OEM in-tank fuel pump module - the OEM module provides fuel to the surge tank, keeping it full, while the pump(s) in the FHST feed fuel to the engine.
