you may need to open up the fuel filler cap. this will creat a vacuum and allow the fuel to flow out.

My 94 1000F needs vaccum on the petcock to drain fuel, I used a brake bleeder to apply vaccum and it flows just fine.

RE: empty gas tank

fire fighter is correct. if the petcock is vacuum actuated, the valve inside wont allow fuel to flow unless there is a vacuum. there are two lines, correct? generally, the smaller of the two line is the vacuum line. if you suck on that (to create a vacuum) i'll bet you a case of your fav. that fuel will flow out the other tube.
