I was changing my filler neck and hoses and saw this ground wire and was wondering where on earth is it suppose to go? Everything around it is fiberglass.

My D has a long ground wire running up to either the filler neck or the roll over valve - I can't remember which but once I get home and can take a look at it I could tell you. I'm not sure if it is factory or someone added it on at some point but it might be one answer.
Otherwise, if it is coming from the fuel pump wiring then it may bolt down to where the rest of the grounds are on the front frame extension, I believe they're located at the driver side radiator support bolt.
It goes on one screw of the fan (one ground for each of them)

I just confirmed my fuel fill neck definitely has a ground going to it. I'd suspect that is likely the wire especially if you just noticed it after replacing the neck.

Domi - your photo shows aftermarket fan solution, stock fans have the ground as part of the harness. Each stock fan connects through a 2 pin connector, later harnesses have 2 black wires on 1 pin, and then a green wire along with a yellow wire on the other pin. Early harnesses seemed to only have 1 green wire on one pin and 1 black wire on the other (it seems that they did not use the capacitor at first). The fan side is only 2 wires which go into the fan, nothing bolts outside.

I also have ground wiring on the frame, but not the same wires of the fans

Thanks everyone. Based on what I am seeing it has to be from the filler neck. I always think if I see a ground wire, it needs to be bolted to the frame, but I suppose the other end of that wire IS on the frame and its supposed to ground something else. It make sense now that you'll want to make sure the neck is grounded for static discharge while fueling.

Yes. That wire makes sure that the filler neck is grounded to the frame to avoid sparking when you hit the filler with the nozzle. Steel cars don't generally have a problem with this, but an essentially plastic car does!
