The pump doesn't know anything... it doesn't have to. Big cars with large unefficient engines will have to stop more often and fill larger tanks. Small cars with hybrid engines and small gas tanks will fill up less often with less gass.

You are making an incorrect assumption...small = fuel efficient. What about sports cars? The Ford Mustang averages 20 mpg while the Explorer averages just 3 less. Some of the more exotic sports cars average just 14 mpg.

A program to tax gasoline based on miles driven is underway in Oregon as a way to pay for road use. It's set at the rate of current taxes to make the technology transition less noticeable, but they hope to bring it into full swing in a few years.

Actually I'm not making an incorrect assumption: small displacement engines designed for maximum efficiency, in small cars, are the most efficent cars on the road. We're not talking 20mpg, we're talking more like 35+. Mustangs and Explorers are both gas whores.
