-15- ABSTRACT OF THE DISCLOSURE A service station dispenser for gasoline with a vapor collection system is disclosed which processes the electrical signal typically produced by the fuel meter which represents the volume flow rate of fuel to the tank to control the displacement volume of an electrically driven vacuum pump so that a simple vacuum intake disposed preferably inside, but not sealed with, the filter neck can be used to collect only the vapors displaced from the fuel tank by the fuel. The vacuum pump is preferably controlled by the same digital processor which calculates and displays volume and cost to the customer, and a single vacuum pump can be used in connection with single point of sale, multiple fuel grade systems or with multiple point of sale, single grade systems for enhanced economy of cost.
