1. A system for monitoring vapor containment in a liquid fuel dispensing facility having a fuel storage system that provides fuel for dispensing by one or more fuel dispensing units, comprising:

  • a pressure sensor operatively connected to the fuel storage system or pipeline system coupled to the fuel storage system to measure the pressure level in the fuel storage system;

    a monitor operatively connected to said pressure sensor; and

    a vapor processor operatively connected to the fuel storage system wherein said vapor processor draws a negative pressure in the fuel storage system when the fuel storage system is not adequately negative;

    said monitor monitors said pressure level in the fuel storage system using readings from said pressure sensor to determine if the fuel storage system contains a leak.
