If you need #13 (Honda Part Number: 46669-S5A-003), diaphragm or one of the other parts separately shown in the attached diagram , the part is separately available from the dealer.
So very interesting….When I called the dealer they told me I had to buy the whole reservoir. I just called again with that part number and they now say it is available
separately as you said. Thanks so much!
