I have and they no longer support that pump, and all their literature on those pumps state that. I can only hope that there is some new old stock around. I did talk to a parts rep today and they were able to get me an alternative to that packing, K667 then cut down to 5 5/8" long. I was incorect when i said cav 4 it is a ca 4 pump
