Abstract
A garage forecourt installation is disclosed in which the fuel dispensing pump is linked to a vacuum cleaning device so that as the fuel pump is switched on suction is made available at a suction cleaning nozzle. The provision of suction ceases on the pump being switched off, or a predetermined time thereafter. The fuel pump can be linked (by a cable) to an electric motor of the vacuum cleaning device so that they are activated simultaneously. A time delay device can be incorporated so that the motor of the vacuum cleaner runs on after the fuel dispensing pump stops.
