A tank 1 for fluid, the tank 1 having an inlet, an outlet 5, and a variable volume element 6, e.g. a bellow, disposed in the tank below the outlet. The element has a first configuration in which it is compressed by fluid in the tank (Fig. 6A). In a second configuration, when fluid is withdrawn from the tank 1, the variable volume element 6 expands to occupy a larger volume; this decreases the volume of the tank below the outlet 5 which is occupiable by fluid. Also, a variable volume element 6 for a tank 1, the element being generally planar and for securing in the tank below its outlet. The element 6 is expandable to increase in volume when a fluid is removed from the tank; and is biased to expand. Also, vehicles including such tanks 1 and elements 6.
