All you need to do is watch the mileage and the fuel gauge. When you get about 250 miles on the tank or the gauge drops to maybe 3/4 empty, fill it up. Do not depend on the low fuel light and you will be OK.

Symptoms of running out of fuel - it will lose power, then pick up again; will do this several times. It may cough. Then it will just stall and not restart no matter how strong your battery is. Just fill it up, pump the pump, and grind the starter until it starts.
