Just look for the fuel pump at whatever airport you land at. Pull up to it and come to a complete stop, your fuel will instant be 100%. Or you can just use the fuel and payload window and do it yourself, wherever you are.
Or...Assign whatever key command you want to "Add fuel quantity" which is the first option on the control assignments list (Settings>Controls>Assignments).
Press this key or button repeatedly at any time and it will "top you off".
I tend to use this after landing, which is fairly realistic, only because the fuel pump placements are usually
very unrealistic in FS9 (compared to real life).
That, and sometimes in RL a fuel truck comes to
you...
But if you're running out of fuel in flight, you need to learn more about how estimated fuel consumption affects flight planning.
