An automatic, virtually leak-free filling system for filling a liquid tank (1), comprises a bulk supply tarlk (3), pump means (12, 22) and a liquid line (5, 11) connected to the bulk supply tank which at its open end is provided with coupling means (9) for a manually detachable, virtually leak-free to a filling neck (25) of a liquid inlet (10) to the liquid tank (1). The system is moreover furnished with overfill protection means which automatically cut off the liquid supply to the liquid tank (1) on reaching a predetermined filling level in the liquid tank (1). According to the invention, the liquid tank (1) is furnished with a localized vapour outlet (15) which, at least during operation, connects to a vapour return line (13). The overfill protection means comprise a float valve (20) which is capable of cutting of the vapour return line (13) when said predetermined filling level is reached. The overfill protection means further comprise a vapour flow detector (16) which is interposed in the vapour return line (16) and is capable of producing an electrical output signal when any vapour in the vapour return line (13) ceases to flow. This output signal is fed to the pump means (12, 22) causing the further supply of liquid to be cut off.
