1990 Chevy Lumina 1990 Lumina Flooding, won't start

My 90 lumina is flooding very bad. When I took off the air filter cover to get a better look it had about a liter of fuel in the cover. I noticed that even with the key off it was dripping fuel out of the air intake where it was filling up the air filter. If I leave it sit for awhile it will start but then it starts sputtering and eventually dies. I am a little unsure where to start so any help would be greatly appreciated.

*UPDATE*

We loosened 3 hoses/lines attached to the throttle body right above the air intake and when we turned the key on fuel started pouring out of what looks to be a vacuum line. We still have no solution any help is appreciated.
