How do you fuel only the internals with a drop tank installed?

To fuel only the internals of a Super Hornet with a drop tank installed, it is essential to manage the fueling system effectively. By leaving the drop tank external pre-check switch out, you disable the fueling capability of the external tank. This ensures that fuel will only be directed into the internal fuel tanks, as the operation of the drop tank is prevented.

The drop tank external pre-check switch is designed to control the flow of fuel to and from the external tank. When this switch is left out, it physically interrupts the fuel line to the drop tank during refueling, providing a safe way to fill the internal tanks without inadvertently transferring any fuel into the external drop tank.

Other options may involve operational aspects that do not specifically address the fueling mechanism needed to achieve only internal fueling, making them less suitable for this situation.
