A post-pay fuel dispensing system in which a fuel dispensing unit is under the remote control of a control console. The dispensing unit is operated by the customer and payment for the fuel dispensed is made after the fuel has been received. Data concerning the amount of fuel dispensed and the cost thereof is transmitted from the dispensing unit to the control console and payment is made at that point. According to the present invention, the dispensing unit is prepared for operation by the taking of certain enabling steps at the control console and thereafter fuel can be withdrawn from the dispensing unit. A particular feature of the present invention is to be found in the fact that the control system for the dispensing unit is not locked-in until the dispensing of fuel is commenced. Thus, if there is improper operation of the switches at the dispensing unit, the operator at the control console does not need again to enable the unit until after the dispensing of fuel commences. Once the dispensing of fuel commences the unit becomes locked-in and becomes disabled upon the individual at the dispensing pump again returning the control switch thereon to "off" position and hanging up the dispensing nozzle.
