Radium Fuel Level Sensor Block-Off Kit
Application: Universal – fuel cells and Radium fuel cell surge tanks with a 5-bolt SAE level sender flange

The Radium Fuel Level Sensor Block-Off Kit seals the 5-bolt SAE flanged fuel level sender opening when a level sender is not being used. It is used extensively by customers running Radium fuel cell surge tanks.
