I dont think I have experienced a fuel leak,at least that I am aware of.
What I normally do to keep a check on my fuel is -

1 - get max range as soon as I start the patrol,at cruising speed.I ask for 5 reports,then take an average.
2 - I then work out my fuel consumption for 24hrs,usually ends up around 520km worth.I then do another fuel check in 24hrs time.The fuel should fluctuate (+ -) no more than around 50-100km,depending on sea conditions.
3 - I then repeat fuel checks at 12:00 each day.
