MY fuel gauge started to show empty when I just topped it off. Now it's all over the place. I might show full when I just filled it but when I turn it off and get back in to restart it it shows empty or maybe half full, you never know what it's going to read. Any ideas?

Check the fuel sending unit in fuel tank, It most probably has poor contacts.

Do you know if the fuel sending unit is external or internal?

It is internal of fuel tank.
If you remove the 2nd row of seat and lift the carpet, you would be able to access the service hole.

Thanks, I have removed the seat and found the access hole but how do you remove the black metal plate to get at the sending unit?

You need a special tool to turn it like a bottle cap to loosen and remove, after disconnecting the hoses and wire connector.
Remember to release the fuel pressure first. Unplug the fuel pump relay and crank engine until it fails to start.
