The present invention discloses a vacuum-assisted vapor recovery system for loading vessels with volatile materials such as liquid hydrocarbons, including gasoline and distillates, which system utilizes a series of interlock premissives and vacuum controllers to maintain a vacuum on the vapor header of the vessel being loaded, which vacuum is within a desired, predetermined level. The system is further arranged and adapted to shutdown the filling of liquids into the vessel should a vacuum leak be detected or should any other malfunction of the vapor recovery system or the liquid filling system arise.
