In an arrangement for limiting the fill level in a fuel tank having a filler neck with a tank inlet end, a valve flap is pivotally supported in the inlet end such that, in an open position, the valve flap is pivoted toward the fuel flow entering the tank during refueling and is connected, by way of a crank arm and a coupling rod to a float which is disposed in an essentially vertical guide tube. The coupling rod extends through the float and has spaced top and bottom stops providing for lost motion coupling between the float and the coupling rod whose weight is sufficient to keep the valve flap in an open position. When the fuel in the tank lifts the float and, after the float engages the top stop, lifts the coupling rod, closing movement of the valve flap is initiated which is then fully closed by the inflowing fuel utilizing the lost motion distance between the float and the bottom stop of the coupling rod.
