RADIUM Engineering 20-1820 Fuel Hanger Surge Tank for Nissan - 370Z

The RADIUM Engineering 20-1820 Fuel Hanger Surge Tank (FHST) is an advanced in-tank fuel system solution designed to eliminate fuel starvation in the Nissan 370Z (Z34 chassis). This innovative design creates a fully functional surge tank inside the OEM fuel tank, addressing the fuel delivery issues caused by the 370Z's saddle-bag style tank and insufficient baffling during aggressive driving conditions.

Key Features:

• Drop-in installation with no grinding, bending, or sheet metal modification required
• Compatible with 1 or 2 aftermarket fuel pumps (pumps sold separately)
• Integrated 1:1 adjustable fuel pressure regulator with vacuum reference port
• Included fuel pressure gauge for monitoring
• Hermetically sealed electrical connections with anodized aluminum acorn nuts
• High-quality ETFE-insulated in-tank wiring
• Compatible with gasoline, E85, methanol, and other alternative fuels
• Anodized aluminum construction with stainless steel hardware

Pump Compatibility (Not Included):

• Walbro GSS342 255LPH
• AEM 50-1200 E85
• Ti Automotive BKS1001 (brushless)
• Walbro F90000267/274/285 E85

This comprehensive kit includes all necessary installation components including relay, fuse, wiring harness, external fuel hoses, fittings, and hardware. The integrated fuel pressure regulator can operate at a 1:1 ratio with boost pressure when connected to manifold vacuum, or maintain constant pressure when left open to atmosphere. Works in conjunction with the OEM fuel module (which requires upgrading to a minimum 340LPH pump) to ensure consistent fuel delivery under all driving conditions.
