Petrol Pump Safety Nozzle is a device for petroleum fuel pumps consisting of a retractable sleeve attached to a nozzle. The sleeve moves upward when it engages the perimeter of a petroleum gasoline receptacle. The sleeve is connected to a trigger release to allow the trigger to move and dispense gasoline. To use the preferred embodiment of Petrol Pump Safety Nozzle, a user inserts the device into a petroleum gasoline receptacle opening causing the retractable sleeve to expose the nozzle and to actuate the sliding trigger release to permit the trigger to dispense gasoline. When this device is placed inside a standard diesel fuel receptacle opening, the width of the opening will prevent engagement with the retractable sleeve and fuel cannot be pumped.
