Vehicle Applicationswith:

• 1989–1994 Nissan Skyline GT-R (BNR32)
• Nissan RB26DETT-powered R32 GT-R models

Eliminate fuel starvation during hard acceleration, cornering, and high-G driving with the Radium Engineering Fuel Hanger Surge Tank (Part Number: 20-0740-00). Designed specifically for the 1989–1994 Nissan Skyline GT-R (R32), this drop-in fuel hanger integrates an internal surge tank into the factory fuel tank, providing a dependable fuel supply for high-horsepower street, track, drag racing, and time attack applications.

Unlike traditional external surge tank systems, the Radium Fuel Hanger Surge Tank installs inside the OEM fuel tank, reducing installation complexity while delivering consistent fuel flow under demanding driving conditions. The integrated surge tank remains full using a dedicated lift pump, ensuring the primary fuel pump always has access to fuel even when fuel slosh occurs during aggressive driving.

Engineered from precision CNC-machined anodized aluminum and premium stainless steel hardware, this fuel hanger is built to withstand the demands of gasoline, E85, methanol, and other performance fuels. Its modular design supports multiple fuel pump configurations, allowing your fuel system to grow with your horsepower goals.

Pump Compatibility

The 20-0740-00 fuel hanger is designed for use with:

• Walbro GSS342 255 LPH Fuel Pump
• AEM 50-1000 Fuel Pump
• AEM 50-1200 Fuel Pump

Note: Fuel pumps are sold separately. A minimum of one lift pump and one surge pump is required for proper system operation.

System Design

The Radium Fuel Hanger Surge Tank combines several critical fuel system components into one compact assembly.

Integrated Surge Tank

Fuel is continuously supplied to the internal surge reservoir by a dedicated lift pump. During aggressive driving, this reservoir ensures the primary fuel pump remains submerged, preventing fuel starvation caused by fuel slosh.

Multi-Pump Capability

The modular design allows installation of:

• One lift pump
• One, two, or three high-pressure surge pumps

This flexibility allows the system to support everything from moderately modified RB26DETT engines to extreme horsepower race builds.

High-Current Electrical System

Heavy-duty electrical studs and chemically resistant ETFE-insulated wiring are designed to handle the increased current demands of multiple high-flow fuel pumps while maintaining reliable operation.

Fuel System Connections

The fuel hanger includes:

• 8AN ORB feed port
• 8AN ORB return port
• Factory-style hose connections
• High-current electrical hardware
• Fuel level sender
• Mounting hardware and fittings

The design allows easy integration with both factory fuel plumbing and aftermarket AN fuel systems.

What's Included

• Fuel Hanger Surge Tank assembly
• Hardware for one to three surge pumps
• Hardware for one lift pump
• Lift pump collector assembly
• Fuel level sender
• Fuel level sender mounting bracket
• Installation fittings and hardware
• DIY wiring kit for one surge pump

Why Choose the Radium Fuel Hanger Surge Tank?

As horsepower increases, maintaining a consistent fuel supply becomes critical. Factory fuel pickups can become uncovered during hard launches, braking, or cornering, creating dangerous lean conditions that can lead to engine damage.

The Radium Engineering Fuel Hanger Surge Tank solves this issue by integrating an internal surge tank that continuously supplies fuel to the engine regardless of fuel movement inside the tank. Its modular pump configuration, premium materials, and direct-fit installation make it one of the most effective fuel delivery upgrades available for the R32 Skyline GT-R.

Whether you're building a high-powered street car, drag car, or dedicated circuit machine, this system provides the fuel stability and scalability needed to support serious performance.
