how to drain fuel tank ?

Well, get yourself a hose long enough to reach whatever you're going to pump the gas into. I believe a 3/8" fuel line hose will do the trick.

Remove cover from end of fuel rail.

Remove schrader valve, as you would on a tire.

Slip the hose over the fuel rail end.

Find the pump priming connector (black single wire connector) it's usually right behind and just below the alternator, hanging loose, with nothing connected to it.

Once everything is ready, supplying 12 volts to that connector will start the pump running. I use a piece of wire with an aligator clip on one end and a male spade connector on the other. The male spade connector goes into the pump prime connector, and the alligator clip gets it's power from the connector supplying power to the underhood light.

Keep an eye on the gas flow, and listen to the pump. You can tell when it starts sucking air, the pump's pitch will change noticeably.

When it starts sucking air. disconnect the power.

DON'T FORGET TO REPLACE THE SCHRADER VALVE!!!!
