Description
Radium FCST-X Complete Refueling Kit- Standard Fill
Application: Radium FCST-X fuel cell surge tanks only
Part Type: Complete standard-fill refuelling kit (filler, vent kit and dump can)
Part Number: 20-0841-00, 20-0841-02
The Radium FCST-X does not ship with refuelling parts, so these complete kits bundle a standard filler solution with a vent kit and a Radium Quick Fill Dump Can. Choose direct mount, with the fill neck and cap mounted on the FCST-X, or remote mount, with a flanged filler on a body panel.
In both versions the vent kit secures directly to the 8AN vent that comes standard on the FCST-X, and the included dump can features a large vent for much faster filling than a typical fuel jug.
Key Features
- Complete Kit: Filler, vent kit and Quick Fill Dump Can in one package
- Direct or Remote: Fill neck and cap on the tank, or a body-panel filler with hose to a tank-mounted elbow
- Vent Kit: Secures directly to the standard FCST-X 8AN vent

Available Configurations
- 20-0841-00: Direct Mount – fill neck and cap mount directly to the FCST-X
- 20-0841-02: Remote Mount – flanged filler (typically body-panel mounted) with 1.5" fuel filler hose to an FCST-X mounted fill neck elbow
