A spare drop‑in pump module for Radium FCST‑X fuel cell surge tanks, this module accepts Walbro GSS342, AEM 50‑1200 or DW440 style pumps (pumps sold separately). Having an extra module on hand lets crews perform fast pump changeouts at events and reduces repair time, while preserving the original tank’s removable lift‑out service architecture.
