Where is the fuel filter button in a Lincoln Navigator?

The fuel filter is located behind the transfer case up on the inside of the frame rail. It is a impossible to change type of deal. I am considering relocating it the outside of the frame rail. The filter is held on by two clips that remove with little difficultly. The problem is the filter seems to fuse to the metal tube. Mine does not want to move at all.

Looks like a bigger hammer will be needed.
