A siphon pipe which extends from the nozzle toward the lower surface of the tank is coupled with the nozzle. The siphon pipe is at least partially disposed within the interior portion of the tank. In accordance with a particular embodiment of the present invention the siphon pipe includes a generally rigid, metallic portion disposed adjacent the upper surface of the tank, and a generally flexible portion disposed adjacent the lower surface of the tank.
