When you push the pin in, a lot of fuel may spray out (what the rag is for). Once the fuel no longer coming out under pressure, you can release the valve.
This is how i had to do it, but if your fuel pump is stock and not hotwired, you can pull the fuel pump relay and start the car. That will cycle all the fuel thats sitting in the lines and the rail through.
