A tank refilling system 110 and method, e.g. for retrofitting to a fuel tank of a combine harvester. The system comprises a controllable flow control valve 122 connected in a flow path between a liquid supply (inlet 112) and a liquid tank 70 (outlet to tank 162); a pressure sensor 130 for sensing pressure upstream of the valve 122; and a controller 132 for controlling the valve 122. When liquid in the tank approaches a full state, resulting pressure changes (e.g. due to a level sensing float valve 160 in the liquid tank partially closing the flow path) are measured by the sensor 130. The controller 132 closes the flow control valve 122 based on the sensed pressure change. This system enables refilling of a tank from a remote location to the filling opening of the tank, for example from ground level for a liquid tank which is raised above ground level, and it implements an automatic shut off function.
