My first reason is that modern fuel pumps are located in the fuel tank so the gasoline can help keep the pump cool. I burnt up a fuel pump once when I ran my tank down to almost empty on a 100 degree summer day. Since then I always keep the tank half full. I figure even when it is not real hot outside, the fuel pump will be less stressed if it is kept cooler. Replacing a fuel pump on a modern car is very expensive, messy and time consuming!!

The other reason is I live out in the country and in case of an emergency may need to drive several miles without time to find gas.

You got me to think,so WTH,I GOOGLED.'can't vouch for the numbers but
