To now answer my own question for a future person who runs into this problem, Pentair part 154512 is a 6 1/2 inch closed wrench that fits the above part for removal. The description of the tool makes no mention that this could be used for removing the bottom of a FNS filter.

Thanks for your response. I just checked the o'ring on the lid and it is dried out and cracked. Off to the pool store tomorrow to get a new one. There are no internals on the filter, Just the stand pipe. I have been using silicone grease for all the o'ring installs and have put it on the lid...
