Come on mate!!!!! Every aircraft has its little quirks, and with the Jabiru the fuel tank gauges usually read less in flight than actual, from the suction being drawn from the gauge (sight glass). I ought to know I own one and although its the BIG brother of them the gauges are much the same.
So if you run out in flight (after takeoff) you can not blame the gauges. In flight you may read up to 30L less perhaps, but you can never read 30L more than actual.
So mate before you spray cr@p like that next time check your facts. Chances are if they ran out of fuel there is a BLO@DY good reason for it. I think it will be something else, unless a fuel checking error has been the case, they are damn economical and you could be guilty for thinking they never run out of fuel as they use so little!!!
