I just removed mine a few days ago. Drive it until the tanks mostly empty to make it easier, or just drop it down on the jack nice and slowly and drain the gas out before reinstalling. Above the tank there's a fuel line that is separated by pushing in two tabs, a breather tube that just slips out of it's hose, and an electrical connecter with a red tab to disconnect. There's enough length in the electrical connector once you pull it free from it's retainers so that you can lower the tank a bit to get more access to the connector. You'll need an extension to get to the nuts in front of the tank. The 4 at the back are super easy to get to as long as your bumper isn't in the way somehow. As long as all 7 nuts come off cleanly you can reuse them. If your skid is too crusty to live then you may have some problems with your straps but you'll probably be able to reuse them. You won't need any bolts if the nuts come off okay and you can start them again.
