The system has a floating device that operates in two stages, that is, the first stage is activated when the volume of liquid inside the tank reaches 95%, reducing the flow by up to 10%. The second stage comes into action allowing the passage of a maximum of 5 L / min, allowing the exhaust of the fuel discharge hose.
