This replaced the old one fine. The center tube pops out. If the tube attached to it pushes on it at all, it will bend the plastic and push it out. That mean you can't have a lot of extra tubing sticking out of the hole during the install or else it will push it out when you crew it into the side. This makes install a little more difficult. Also, it can only fill so fast with a hose or jerrycan or the rest just runs out on the ground.
