Abstract: A fuel management system for use in the operation of a fleet of commercial vehicles, comprising a fuel supply means comprising a fuel pump connected to a fuel dispensing nozzle by way of a flexible fuel delivery hose. A fuel management system is coupled to the fuel pump for controlling the amount of fuel dispensed via the nozzle. One end of a fibre optic is carried by the pump nozzle for receiving information from a radiation transmitter on any of said commercial vehicles when the pump nozzle is inserted into the fuel entry port of that vehicle, the other end of the fibre optic being positioned to supply the information to the fuel management system. The fibre optic is run from the top of the nozzle, through a special fitting into the interior of the hose, the fibre optic then running the length of the delivery hose, surrounded by the fuel product, until it reaches the region of the fuel pump, where it emerges from the hose via a gland and runs on to the fuel management system.
