Yes, you can find one at most dealerships..........but, it isn't critical that you have it. It is just mainly for very rainy weather. This time of year, that usually isn't an issue. Be sure you give the dealer the name brand of your regulator as each brand has their own. Amazon or E-Bay probably have one at less money as well. Maybe $3 or so for most.
