If it is the same as a 2.6 fuel tank:
There is a small keyed nut at the bottom. You need a flat head screw driver that is notched in the center.
After you remove that, do not man handle the body as it is fragile.
I believe you may need to bend the tabs on top to remove the shell. Again be gentle.
I assume you are trying to fix a dead or jumpy gauge. Also be careful with the thin 2 wires in there when you are wiping them with solvent.
When you put it back together most likely the cap will start leaking fuel when tank is full. You will need to purchase new O-rings and really clean the surfaces. I had to lightly sand mine to make it smooth again.
Good luck with this.
