HELP!!fuel pump question

[Short1]

hey all, ok, heres the deal. MY girlfriend has a 2000 mustang v6. The fuel pump took a crap sunday and i'm in the process of trying to drop the tank. I cant get the siphon into the tank to empty it, so i figured i would just pull the filler neck from the tank and siphon from there, since it has to be pulled anyway. Heres the problem, I removed the bolts up top, and in the trunk, also unhooked the clamp by the tank, cut out the grommet like it says and the neck moves quite a bit now BUT....i cant get it to come out, is there something i'm missing??? Never done this before, so i'm taking it as it comes...PLEASE help ASAP. THANKS!!!!
