Here's a quick How To that I did today, shouldn't take more than one hour to do it all.
First, get the rigth tools:
Take the Seat off, Loosen all bolts that hold the tank and syphon as much gas as you can before doing anything else, hopefully you got it down to the Warning Light and you have less than a gallon.
Once you have a nearly empty tank, prop it up with something and disconnect all of the fuel lines going to the tank. The Main Fuel line has a coupler, this is the fuel line that shoots out fuel when the ignition is enabled.
Do not disconnect the Electrical Components from the Fuel Pump yet, you will need this to empty out the tank. I used the overflow fuel line and connected it to the Main Fuel Line nipple. Make sure all other hoses are disconnected.
Route the hose to the gas can or whatever you are collecting the gas in, and set the tank back down in it's normal position, you can then turn the key on and the fuel pump will shoot out the remaining fuel - it might take 2 or 3 times, but this will dischrage almost all the fuel from the tank (if you did not syphon gas out, you might have to do it a bit more.)
Once you get all that fuel out, Disconnect the Electrical connectors from the Fuel Pump and place the tank on a pan and get ready to remove the fuel pump.
Remove the Allen Bolts only, once all are out, pull the Fuel Pump out till it catches, there is a small catch that you can push in with a flat head screwdriver.

Once that is out you can get the remaining fuel out (less than half of a soda can)
And that's about it without making a mess or getting fuel all over yourself. Replace Fuel Pump and Gas Lock onto the new tank, re-connect all hoses - remember the coupler for the main line and connect the fuel pump and set it all back down. Put gas in before locking tank in place and give it a quick check for leaks. Hope this helps.
