Back to basics, forget what the fuel guage is telling you when it cuts out. When it does cut out, is it out of fuel, or how much fuel can you get in it when this happens. What I am trying to say is that just because it says it's got 1/4 of a tank, has it? The fuel guage it self can be adjusted. Have you thought about this. Any futher quetions please reply (
