Radium Extension Kit for FCST-X

Application: Radium FCST-X 20-1990, 20-1991 and 20-1992 series
Part Type: Surge tank extension kit for FCST-X
Part Number: 20-1989


The Radium Extension Kit adds 1.2 L of volume to the surge tank of the FCST-X and lowers the one-way fill valves for better fuel starvation protection at low fuel levels. An anodised aluminium canister mounts between the top plate and the existing surge tank canister, and a longer stainless steel pump bracket replaces the original.

The kit makes the module 94mm (3.7in) taller, so it is intended for deeper fuel cells such as the Radium R14A and R22A.

  • Lower Fill Valves: Improved starvation protection at low fuel levels
