I did this this past Saturday. So far so good. Awesome write up. In my experience it would have been nice to have a vise, after you pull the pump out it can be a challenge to break some of the bolts to change out the o0rings. Would have been much easier to put it in a vise and work on it. Other than that the update is pretty straight forward. I've done 99% of the maintenance on my car however I've never done something like this before. I thought it was very interesting to learn the inner working of the pump, i dunno guess that the technical nerd in me. Did anyone ever have any problems that showed up later after doing the rebuild?
