Radium Engineering FCST-X Fill Neck Block-Off Kit

The Radium Engineering FCST-X Fill Neck Block-Off Kit changes, caps, or adapts the filler-neck arrangement on a compatible Radium fuel-cell installation. It is intended for custom fuel-cell layouts where the filler location or refueling method differs from the standard configuration.
