I would guess that it's a cooling vent for some engine component, but to know for sure youd have to find the manual or something for the F/A-18E.

They provide over-pressure and over-fill relief for the internal tanks,

@FoxThree Are you sure that is correct because in that paragraph it says 'The vent lines connect all internal tanks and are ported through the fuselages and vertical tail vent tanks to outlets located on the side of the vertical tail.'
The vents I am referring to are on the fuselage.

On page 55 it points to the top of fuselage near the base of the tail for the location of the vents.
