Yes there is a rubber seal in there. Easy to replace on that item. Not so easy on the next layer down which should not be disturbed if it is not leaking. If you don't know what you are doing it will give you a world of pain.
just to clarify, the seam that the arrow is pointing to is the one with the rubber seal? cheers for your patience but my knowledge of engine block and fuel system is quite poor.
