1992 Chevy S-10 Doesn't want to run

I was on the way to the gas station adn it ran out of gas. I had somebody bring me some and I poured it in. I started it and it was running really ruff. It was so ruff that I had to get it towed home. I figured it was the fuel filter plugged so I changed that but it still runs so ruff that it will die if you don't sit and pump the gas. Any ideas?

Its the 2.8L v-6 with the throttle body.

Thanks,
