I will say that for some strange reason Willis kept popping the pop-off valve off the pump at Ming in Sept. So what ever one you chose to go with it will in my eyes need a better bolting system to hold it in place plus a special restrieghnt sytem. It doesn't take much for a restrieghnt system as Willis proved by using a small ratchet strap. But there is one, to my knowlage in Lake Ming.
