A scene I did just for fun (let's say just for phun )
Drag the tank over the pump, then press I to close the arms and then W to spawn water; when you've done filling the tank press W to stop spawning water, then press C to close the tank (press again C to open it and let the water exit), press I and O to let the arms open and voila, you have a tank filled with water ! The tank can resist to high pressures of course. As I said before, just for fun !
