Abstract: A method and apparatus for preventing a dense liquid such as diesel fuel from being dispensed into a storage tank that contains a less dense liquid, such as gasoline fuel and vice versa. The unloading process happens by gravity through a vertical down hole. The invention uses the gravitational flow of the fluid, a movable float that is moved by contact with a fluid of a predetermined density, and a magnetic member to activate the stopping feature.
