Description
Radium Engineering developed the FCST-X Spare Drop-In Pump Module (Bosch BR540 or DW400) 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-cell surge-tank system combines the anti-starvation function of a surge tank with compact in-cell packaging. This architecture is aimed at motorsport builds where fuel delivery must remain consistent under sustained lateral and longitudinal load while minimizing external plumbing and component count.
Product-Specific Details
Spare fuel pump module for Radium FCST-X fuel cell surge tanks. An extra module assembly allows for quick pump change-outs during competitve events. Pumps sold separately.
Technical Notes
Pump selection should be based on fuel type, target power, pressure requirement and whether pumps will be staged. Fuel-cell depth, top-plate pattern and service access should be confirmed before ordering.
Radium Part Number
RAD20-1997
Enthusiast Notes
For time-attack, endurance and race builds, integrated surge control can simplify packaging while keeping the pressure pumps immersed and supplied during sustained G-load.
Before Ordering
Confirm the fuel-cell opening, internal depth, pump family, pump quantity and whether the selected SKU includes pumps. Verify motorsport-rule requirements for the complete fuel-cell installation.
