The Radium Engineering 20-0700 FHST (Fuel Hanger Surge Tank) Add-On Kit is designed to upgrade compatible Radium Late Nissan Fuel Hangers by adding an integrated surge tank for superior fuel starvation protection. Ideal for high-performance street, drag, drift, and road racing applications, the FHST maintains a constant fuel supply to the fuel pump during hard acceleration, cornering, and braking.

Designed for use with Walbro GSS342 or AEM 50-1200 fuel pumps, the modular system supports single or dual fuel pump configurations and is also compatible with many modern brushless fuel pumps. Its CNC-machined anodized aluminum construction delivers outstanding durability while remaining compatible with gasoline, methanol, and ethanol-based fuels, including E85.

Why Upgrade to the Radium FHST Add-On?

As vehicle performance increases, maintaining a consistent fuel supply becomes critical. During hard launches, cornering, or braking, fuel movement inside the tank can uncover the fuel pump pickup, leading to fuel starvation and unstable fuel pressure.

The Radium 20-0700 FHST Add-On Kit creates a dedicated surge reservoir around the fuel pump, ensuring continuous fuel delivery even under extreme driving conditions. Its bolt-on modular design integrates seamlessly with compatible Radium fuel hangers, making it an excellent upgrade for high-performance Nissan fuel systems.
