I believe there is only one screw which holds the tank in place. It's easy to see, so that part is easy. The difficulty is that there are two hoses that connect to the top side of the reservoir tank and Honda has cut the hoses a little too short. Can be pretty darn frustrating trying to reconnect those rascals. Some guys use long needle nose pliers with a bend in them.
