Don't know if yours is the same as used in our '04 Monterey. Don't have it anymore so I can't send you a picture.
At about year 1 the valve slipped a little in the way it was attached. As BJ operated the switch, I could see the valve move in its mounting bracket. In effect, it was fully operational but could not close all the way. It was in an awkward location but I was able to "improve" the attachment with some ordinary stainless steel wire so that it would fully close.
I know it sounds like a bandaid type repair. In fact it was! But, 10 years later when we sold it, it was still working without leaks.
