Abstract: A fill cover assembly for a liquid fuel storage tank of a road tanker, the assembly comprising: a seat member having a frame, the frame defining a fill aperture, the frame being configured to be fixedly coupled to a base plate of a liquid storage tank, the base plate having a plate aperture formed therein, thereby to form a fluid-tight seal between the seat member and the base plate around said plate aperture; and a fill-cover coupled to the tank and arranged to be moveable with respect to the frame between a closed condition in which a fluid-tight seal is formed between the fill-cover and the frame and an open condition in which fluid may be passed through said fill aperture to fill said storage tank, wherein the assembly is further arranged to allow venting of pressurized fluid from the liquid storage tank in the event that a pressure of the fluid exceeds a prescribed value.

Abstract: A nozzle assembly operable to deliver fluid to a tank to be filled and to sense a level of fluid in the tank, the assembly having a fluid outlet and a sensor portion, the sensor portion comprising a pressure sensor provided in fluid communication with a sensor conduit, the sensor conduit having a sensor conduit aperture provided therein, the assembly being operable in use whereby when a level of liquid in the tank being filled rises above a level of the sensor conduit aperture, the sensor conduit aperture is closed by the liquid and a pressure of gas trapped in the sensor conduit increases thereby indicating a “tank full” condition, the assembly being arranged to detect the increase in pressure of gas and to generate a pressure increase signal indicative of the in crease in pressure when the increase in pressure is detected.
