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. 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.

Radium Engineering does not assemble these when purchasing an FCST-X. This kit must be installed by the end user.

INCLUDED

• Anodized aluminum canister
• Stainless steel pump bracket
