A liquid fuel dispensing system having a plurality of dispensing pumps each generating electric pulses according to the volume of fuel dispensed and a central control where payment is made. A data transmission link couples each pump to the central control and each pump has a pulse store which accumulates pulses generated by the pump during a dispensing operation. A sampling mechanism at the central control samples the outputs from the pulse stores which are updated at each sampling. First and second storage elements are provided to store information at the central control relating to previous pump transaction whereby such pump can be cleared for use by second customer before first customer has paid.
