I ordered the above pump and a new ring seal for the OE contour pump. I've been looking through various how-tos on it but it seems there are different ways to do it. Some people swap the whole assembly, and others, as I understand it, change just the pump itself. I'd like to keep this as simple as possible, what's the best way to do it?
Also, it looks like a real pain getting that lock ring back on. How did other people manage that?
