A float device for use in drawing liquids such as fuel from a tank or other reservoir, the device comprising:
- a liquid pick-up arrangement arranged to rise and fall with the level of liquid in the tank, and a liquid pick-up duct which comprises a flexible tube having its free end coupled to the liquid pick-up arrangement;
- wherein the liquid pick-up arrangement comprises a float and a float housing, the float being disposed substantially within the float housing, an outer surface of the float and an inner surface of the float housing being spaced from each other to define a liquid pick-up passage therebetween, the liquid pick-up passage being in fluid communication with the tube of the liquid pick-up duct;
- and
- wherein the liquid pick-up arrangement is arranged for movement within an elongate member which encloses the arrangement and the flexible tube and which comprises an open lower end.
