ABSTRACT:
A fuel storage and dispensing system is provided that is effective in reducing the emission of harmful volatile organic compounds. In accordance with one embodiment of the present invention, a fuel storage and dispensing system is provided comprising at least one storage tank, an air exhaust port, at least one fuel dispenser, a fuel dispensing nozzle, a rigid, fuel dispensing spout, a boot, a pressure relief chamber, a filter system, and at least one pump. The rigid, fuel dispensing spout further defines a non-coaxial fuel tube. The boot is configured to maintain a sufficient level of vacuum within the fuel storage and dispensing system. The boot is further configured to prevent fresh air from entering the fuel dispensing nozzle. The present invention also includes additional embodiments including a pressure relief chamber that is effective in compensating for high temperature pressure build-up in a vapor assist hose, a fuel dispensing nozzle and spout assembly, a vapor recovery boot assembly, and a Venturi shut-off assembly for a fuel dispensing nozzle and spout.
