this would be a great suggestion for Myth Busters. The only way to know would be to place some sort of "flow meter" in the fuel line, or to drain the tank and place only 1 gallon of fuel, and seeing how long it takes to run it out of fuel, but no one who owns a diesel is going to let a 6.0 run out of fuel on purpose so flow meter or nothing, call Myth Busters!
