OVERVIEW
This extension kit permits an additional 1.2 liters of volume for the fuel surge tank found in many FCST-X (10yr special edition). This also lowers the 1-way fill valves for increased fuel starvation protection at low fuel levels. As shown below, the anodized aluminum canister secures between the top plate and the existing surge tank canister. 

Because it is 3.7in taller, it is not compatible with shallow fuel cells. A longer stainless steel pump bracket replaces the existing pump bracket. The parts shown below in blue are provided.

NOTES:
1. Fuel cells must be at least 10.8in (275mm) deep. This is measured from the top sealing surface to the inner floor of the fuel cell.
Radium Engineering does not assemble these when purchasing an FCST-X. This kit must be installed by the end user.
2. If installing this extension kit into 20-1991-00 (for Bosch BR540 or DW400), Radium P/N: 14-0691 adapter fittings are required. The quantity needed is directly related to the amount of the fuel pumps installed into the fuel surge tank. These adapter fittings can be found HERE.

INCLUDED
-Anodized aluminum canister
-Stainless steel pump bracket
-Large ID fuel pump tubing
-Small ID fuel pump tubing
-Submersible fuel hose
-Stainless steel hardware
