If you just want to drain the tank you can disconnect the fuel line, either under the car or in the engine compartment. Then connect a piece of hose and put it into an empty gas can.

Then, pressurize the gas tank with an air hose.

You can do this by wrapping a rag around the hose nozzle and stuffing it into the gas filler pipe.

Or, if you have an old inner tube, you can make a fuel tank pressurizer.

Cut out a circle of rubber with the air valve in the middle. Clamp the rubber onto your filler pipe with a hose clamp. Pressurize the tank with your air hose.

You don't want to put more than 5 or 10 pounds of pressure on the tank. Neither of these methods will allow much pressure. The rubber method is kind of cool because the rubber bulges up and lets you see the pressure.
