If you have done it before on your own bike and know where every connector is you can do it without disconnecting the tank but its a pain, better to remove the tank.
I have changed a few without removing the tank, last one was only a few weeks ago on my 83 RS, didn't disconnect the tank and just wedged it up enough to access the connector.
But I now keep a few 5 litre containers and a little bulb primer and pipe I got from Tills.de for about €3.50 and its a doddle to empty the tank and just put the petrol into one of the other bikes.
