An opposite second end of the first conduit is configured for communication with a source of bulk cargo that is separate from the hopper. A second conduit has a first end that is also connected to a portion of the housing of the hopper and communicates with the interior portion of the housing. A second end of the second conduit is also connected to a portion of the housing of the hopper and communicates with the interior volume of the housing of the hopper.
