Maybe I'm older than dirt or it's because I was raised in the country, but I remember a station that had the gravity flow pumps. My dad would get gas there when I was young and I even worked there when I was 13 or 14 years old.
Here's a pic of what they look like. Not sure of the gas price though, but I know we would get 1 or 2 dollars worth most of the time.
