Radium Engineering FCST-X Spare Drop-In Pump Module (Brushless Ti Automotive E5LM)

Radium Engineering designed the FCST-X Spare Drop-In Pump Module (Brushless Ti Automotive E5LM) as a purpose-built solution that keeps a dedicated reservoir of fuel around the high-pressure pump or pumps to reduce fuel starvation during hard cornering, acceleration, and other high-load driving. By integrating surge-tank functionality with a fuel-cell system, the setup is well suited to track, competition, and high-performance builds that cannot tolerate inconsistent fuel supply.

Key sizing for this version includes compatibility with Ti Automotive E5LM, so it should be matched to the rest of the system before installation. Pump model and quantity are part-number-specific. Match the surge-tank configuration to the exact pump family being used.
