I've pulled my vacuum pump numerous times in order to mess with the IP timing and injectors. I've never noticed anything that would lead me to believe orientation mattered. It seems that it rotates about its axis, since every time I pull it out it is in a different location about its axis. I realize that the push rod has a flat "side" to it, but I thought that was just for lubrication purposes. Would you mind sharing with me how the orientation of the push rod matters?
