I'm working on my first pump restoration, a Wayne 515 and am missing one part on it. It's the serve valve and handle assembly unit that attaches to the top fill pipe just under the glass cylinder bottom head. I already have the serve valve handle adapter that attaches to the serve valve assembly and rod assembly that is inside the pump and attaches to the drain back lever at bottom next to the nozzle. If you have this part or know where I can find one please let me know as the pump looks incomplete without it. Thanks, Steve
