DEFUELING
Pressure defueling is the quickest and most common way to defuel. The
tanks can be defueled either simultaneously or independently. The standby
pumps are used for pressure defueling. If a large quantity of fuel must be de-
fueled use GPU power supply, otherwise the standby pumps will drain the bat-
teries.
If standby pumps not available for defuel, suction defueling by the fuel truck
can be used. However, it’s not so effective and takes longer time. At suction,
the tanks can be defueled simultaneously but only the right tank independent-
ly, due to the fuel system design.
