Filling units for supplying small tanks or the like with gasoline, kerosene, or other flowable materials which attach to an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank and allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, manipulation of the displacer section, as for example by withdrawing a section of the overall unit upward opening a valve or movement within the tank itself, causes all the liquid remaining in the funnel up to such predetermined level to be accommodated within the tank by occupying the volume previously occupied by the displacer section and thereby completing the filling of the tank to a full condition without any spillage. The overall unit may be such that it is intended to be removed from the tank after each filling operation (and preferably stored in an optional, integral storage compartment), or it may be designed to fit permanently within a tank inlet and to be movable downward to a storage orientation, which allows the replacing of the protective screw cap that normally closes the tank.
