In the documentation I posted above, the tech support # is outdated. It is 850-575-7877. In the documentation, they keep saying "Early 722.3 vs. Late 722.3 adn 722.4". I called them about that and they faxed me these two docs that clears up the confusion. Trouble is, you have to remove the valve body to be 100% sure!
I'll post all the docs that came in the box later tomorrow.
