Mark talked with the driver to understand why the two hose system was used, and also why it was not implemented on the standard delivery nozzle, allowing vapors to escape from the vehicle gas tank.
After the tanker driver left, Mark drew an idea for a Vapor Recovery Gasoline Nozzle and submitted it to the Chevron Station Management as an employee suggestion.
Mark was included in the design and development as the original Vapor recovery gasoline nozzle, which was manufactured and delivered by Huddleson.
Mark was appointed as the Vapor Recovery Gasoline Nozzle executive for the 2 year implementation program, his duties were to train and oversee the installation and maintenance of 124 Chevron Service Stations within San Diego County.
