Sorry Art. Finished and buttoned up.
The clamp, in its current position, gets pushed down toward the end of the hard fuel line, over the part that is slightly larger circumference, about 1/2 inch. That clears the fangs from the end of the fuel line. Then it pops right off. If you find yourself in a bind, PM me and I'll try to re create and take pictures of the top clip.
I removed the bracket holding the oil sump tank that is closest to the firewall. I needed that space to get at the size 27 star bolt that holds the filter bracket to the frame. That little bolt, removal and replacement, is a real pain in the a$$.
I undid the three bolts that hold the transaxle cooler to the brackets. I did not disconnect the cooler, but that allowed me to move it outside toward the side scoop.
After removing the top fuel line from the filter, I removed the filter from the frame and pushed it under the frame in order to remove the lower fuel line using the open space created by moving the cooler aside.
Glad I don't have to do this again for a looonnnggg time.
ADDED:
Here are two photos I did take when removing the top safety clip. In this one, I've moved the top of the clip off the hardline and that's when the lower part of the clip will not clear the flange. You can also see how the end of the hard line expands in size a bit. I then replaced the top of the clip on the hardline, pushed it down and off it came.
Here is the safety clip removed. It shows the fangs on the bottom of the clip and the top part of the clip that must be pushed down over the hard line.
