Radium Engineering FCST-X Extension Kit (3.7in / 1.2L Capacity) - Universal
This Radium Engineering extension kit (SKU 20-1989) adds 1.2L of surge tank volume to compatible Radium FCST-X units. It also lowers the one-way fill valves, improving protection against fuel starvation when the cell is running low.
The 3.7in tall anodised aluminium canister fits between the top plate and the existing surge tank canister, and a longer stainless steel pump bracket replaces the original. The kit is supplied for user installation and is not fitted to FCST-X units from the factory.
Note: Fuel cells must be at least 10.8in (275mm) deep. Compatible FCST-X units: 20-1990-00/01/02/03, 20-1991-00 and 20-1992-00/01/02/03 only. Compatible Radium cells: 20-0614 (R14A, 14 gallon) and 20-0622 (R22A, 22 gallon) – not R06A, R10A or R11A. When used with FCST-X 20-1991-00 (Bosch BR540/DW400), Radium 14-0691 adapter fittings are required, quantity depending on the pumps used. Installation by a professional is recommended.
