I cut a 12 x 12 x 12" U into the original tank to get in there and clean it out and then welded that up years ago. The internal return line finally split so I need a replacement. Capping the hole is not an issue for me.

Let me ask this way....If I cut the hose from the tank to the pump, how much more needs to be done above that cut to get the tank out? As I recall there is a seal of some sort between the trunk and the pumps/filter etc. but I don't remember what I had to do to deal with that part of the removal.

Thanks!
