Description
The Radium Engineering FHST Add-On for Nissan S14/S15 & R33/R34 GSS342/AEM is intended for performance builds that demand a more deliberate approach than simply adapting the factory hardware. It gives the installer a Radium-specific foundation for the listed application.
Why This Upgrade Matters
A fuel-hanger surge-tank assembly places the surge reservoir and pump hardware inside the factory tank, combining upgraded fuel delivery with anti-starvation control while retaining a more integrated installation than a conventional external surge tank.
Product-Specific Details
This kit is added to a compatible Radium Nissan fuel pump hanger to convert it to a Fuel Hanger Surge Tank (FHST). This prevents fuel starvation from occurring during aggressive driving.
Fitment & Application
Application: Nissan S14/S15 & R33/R34 GSS342/AEM
Fitment style: Application-Specific
Technical Notes
Pump compatibility is configuration-specific. Plan pump quantity, current draw, feed and return line sizing, filtration and pressure regulation as one system rather than treating the hanger as an isolated component.
Radium Part Number
RAD20-0700
Enthusiast Notes
This approach is attractive for dual-purpose cars because it packages serious fuel-delivery capacity inside the tank instead of adding a large external surge-tank assembly to the cabin or trunk.
Before Ordering
Confirm vehicle, pump family and quantity, wiring requirements, filtration and regulator/plumbing strategy. Some configurations require additional pump-specific hardware.
