If you're truly lazy like me and don't want to drop the fuel tank, you may be able to get away with using a pair of longnose spark plug boot pliers like this.
This was on a later (2011) van with the vertical outlet; the screwdriver was used to pry the ears of the yellow locking piece out of the way, then to pry the plug upwards (between the yellow and black in the photo below) while depressing the lock tabs with the pliers.
Once I had it out and could see what the yellow piece actually looks like, I think you're supposed to just slide it outwards?
