check out this video by S&S. It has very good info regarding CP4 and CP3 pumps.

I realize this is an older thread but I just wanna say that I did the S&S Emissions compliant CP3 in my 2013 LML and have no complaints thus far, worked just fine emissions intact and still works just fine with the emissions components on vacation. I wouldn't hesitate on spending the money on it again. I also realize that there are some upgraded CP4 options but like others have said, its the internal design that really helps ruin your fuel system when it goes. From what I understand, if a CP3 dies, it is just dead and you have to swap it out but it shouldn't take the injectors and other components with it.
