Well kind of depends where its at on the tank. And also what you really want. I had the same thing happen one on just an old tank, and one on a tank I sat on something hard and dmg the seals under it. But if your you mean the actual inside the tank, Id re do all of it IMO because your going to have to take it all out anyways so.. might as well do it now.. then more later. If its on the outside you can just do that little part. I had an issue on the bottom black liner and I took it all off and replaced it.. But its up to you mostly. |
