I know I've heard of people using it, I've heard a couple vague recommendations to do it, but I can't seem to find any testimonials from anyone who has done it. Well, it's time for me to replace my pump and if I can get the Focus pump for $100 that'll be much nicer than the Contour pump for $300. Does anyone have the facts, if it's a drop-in job or if anything needs to be modded? What part number you got?
