Upgrade your Nissan Skyline GT-R R32 fuel system with the Radium Engineering Fuel Hanger Surge Tank (FHST) Part Number 20-0742-00, designed specifically for Walbro F90000267, F90000274, and F90000285 high-flow fuel pumps. This advanced in-tank fuel delivery solution provides consistent fuel supply for high-horsepower RB26DETT builds by helping prevent fuel starvation during aggressive acceleration, braking, and high-G cornering.

The Radium FHST replaces the factory fuel pump hanger with a fully integrated surge tank system that installs inside the OEM fuel tank. By combining a fuel hanger, surge reservoir, and multi-pump capability into one compact assembly, this system delivers the benefits of an external surge tank while maintaining a clean OEM-style installation without additional mounting requirements or external plumbing.

Designed for demanding street, drag, drift, and track applications, the 20-0742-00 provides a scalable fuel solution capable of supporting increased horsepower levels while maintaining reliable fuel delivery under extreme driving conditions.

Advanced In-Tank Surge Tank Technology

Fuel starvation is a common concern in high-performance vehicles when fuel moves away from the pickup point during hard acceleration, braking, and cornering. When this occurs, fuel pumps can become exposed and draw air, resulting in inconsistent fuel pressure and potentially dangerous lean conditions.

The Radium Engineering FHST solves this issue by incorporating an internal surge reservoir that keeps fuel surrounding the high-pressure pumps. A dedicated lift pump continuously supplies fuel to the surge tank, ensuring reliable fuel delivery even during extreme driving conditions.

Why Choose the Radium 20-0742-00 Fuel Hanger Surge Tank?

As RB26DETT power levels increase, fuel system demands increase as well. Larger turbochargers, increased boost levels, ethanol fuel conversions, and track use require a fuel system capable of maintaining consistent fuel pressure under all conditions.

The Radium Engineering 20-0742-00 Fuel Hanger Surge Tank provides a professional motorsport-inspired solution by combining a high-capacity fuel hanger and surge tank into a direct-fit in-tank assembly. Supporting multiple Walbro high-flow fuel pumps makes this system ideal for serious performance builds.

Whether you're building a high-horsepower street GT-R, drag racing setup, drift car, or dedicated track vehicle, the FHST provides the fuel reliability needed to safely support increased power levels.
