Description
Radium Engineering developed the Fuel Hanger Surge Tank for Mazda RX-7 FD Microglass around the needs of modified street and competition cars, where component compatibility and clean system layout matter as much as outright capacity.
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
Includes, feed line, fittings, and Radium fuel filter for easy installation in Mazda FD RX-7. To be used with Radium FD RX-7 in-tank fuel pump hanger system.
Fitment & Application
Application: Mazda RX-7 FD Microglass
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.

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.
