Product Description

The Radium Engineering 20-1830 Fuel Hanger Surge Tank (FHST) is designed to address fuel starvation issues in high-performance Nissan and Infiniti vehicles. By integrating a surge tank within the OEM fuel tank, it ensures consistent fuel delivery during aggressive driving conditions, such as track use or spirited driving.

This FHST supports dual internal fuel pumps (Walbro GSS342 or AEM 50-1200) and includes an integrated 1:1 adjustable fuel pressure regulator with a vacuum reference port, allowing for precise fuel pressure control. The system maintains the functionality of the OEM venturi jet pump, ensuring proper fuel transfer within the tank.

Constructed from anodized aluminum and featuring high-current electrical hardware, the 20-1830 is compatible with gasoline, ethanol (E85), and methanol fuels. Its drop-in design requires no cutting or welding, making installation straightforward. For early model vehicles, specific fuel level adapters are required to ensure proper fitment and functionality.
