Reserve/second fuel tank

Do you run out of squirt often then? If you know that your car has a range of 100-120 miles and your going to do a long run, would you not start thinking about finding fuel when you had 1/4 of a tank left? I've sat here for past 30 mins trying to come up with a fancy plumbing solution using 2-3 tanks and my wife just said 'every body has smart phones google petrol stations' which thinking about is a lot simpler.
