ABSTRACT:
A pressure-monitoring system for detecting pressure between a fuel pump in a fuel storage tank and a fuel dispenser in automotive fuel service stations. The pressure-monitoring system utilizes a pressure-sensitive switch interconnected in the dispensers. A controller is associated with the pressure sensitive switch and the fuel pump utilized to extract fuel from the fuel storage tank. Upon the detection of a leak in the lines between the pump and the fuel dispenser, the controller interrupts the electrical circuitry to the pump and disables the pump until the leak has been located and repaired.
