The other thing is that it will make life much easier and less risky if you take the fuel tank off completely rather than trying to work underneath it. Suggestion ... arrange for doing this procedure with the fuel tank almost empty, it's a lot easier to handle!!
On the '04 - '05, to take the fuel tank off completely, after undoing the bolts, unplug the connector on the left side that was underneath the left trim panel (leads to fuel pump - you'll find it easy that way). Then you will need to unplug the fuel line. Set the fuel tank down before doing this, switch on the ignition key and crank the engine for a couple seconds. It won't start with the fuel pump unplugged, but this will de-pressurize the fuel rail so that you don't spray fuel everywhere. Now, using your fingers, press together the pink projections on the end of the fuel hose and simultaneously push those projections into the connector. This will push the little pink locking device out of the fuel connector on the other side (doesn't need to come completely out). Then you can pull the fuel hose off, and then take the fuel tank completely off the bike.
