Taking the seat off is a five minute job. the tank, however, plan on a good 3 to 4 hours to get it out. Take your time, take LOTS of pictures, and be sure to use the DIY article on this forum. It is a lifesaver. And if you still have any questions go ahead and ask because all of us are here to help. I have a few pictures of my tank removal on my profile. If you want any more, just ask.
