The fuel gauge is actually a voltmeter (if you are familiar with those). Instead of 12 volts at the top and 0 volts at the bottom, you have an "F" and an "E" printed on it. Does that clearify it? Hope you have some electronic knowledge.
awesome explaination.. :goodjob:

It's simple.
My car goes ~370 miles before it runs dry. So at 300 miles, I know I have roughly 70 miles until empty.
It's about as accurate as that stinking computer on "luxury cars" nowadays too. Since all they do is take an average based on your current MPG (using fuel rate and fuel consumption) and how much fuel you have left in your tank.

In that respect, the 1927 Ford Model T had a similar computer.
