How to remove the gas from the tank of a non-running 1994 Chevy Astro van?

I'm 99.9 % sure that the fuel pump is shot. Unfortunately, the pump is INSIDE the fuel tank, so the tank must be removed first. My problem: the tank is over half full, and I can't run the engine to use up the gas. Tried siphoning today, but the filler neck seems to be siphon-proof. Any SAFE ways to remove the gas? If possible, I'd like to be able to collect the gas and use it, instead of watching about 35 bucks go bye-bye.
