Go to the hardware store and buy 4 or 5 feet of clear flexible hose with 3/8" id. Put one end in the bottom of the tank, letting it droop down over the back of the deck to about the bumper height. Standing up suck on the hose until gas comes up out of the tank and your can see it as it goes down to the lowest part of the hose.
STOP SUCKING, put your finger over the open end of the hose. Then take the end that you had in your mouth and place it in an approved gas container and take your finger off of the hole. You may need to move the hose around in the tank a bit to get all of the gas out.
Or if you don't like the thought of sucking the gas up, fill the hose with water, hold your finger over one end, put the other end in the tank, lower the other end into the gas container and take your finger off of the end to let the water and gas flow into your container. You could also let the water run in a different container until you saw gas coming out, then swith the hose to the gas can.
Or, just go buy a syphon kit.

PS I don't think you have to remove the tank to get the sender out. It comes out of the bottom of the tank. At least it does on 63's.
