Well, it's not an Alero, but I helped a buddy of mine change one on his Blazer. Start by removing as much gasoline as possible to make the tank lighter. Then put a jack under the gas tank and remove the gas tank straps. Then ease down the tank after disconnecting all plugs and lines (if possible). Then you will need to remove the fuel pump lock ring. It's a metal ring that goes around the opening of the gas tank where the fuel pump goes in. You may need to tap it with a hammer and chissel to break it loose. I think it turns counter-clockwise, but you may want to check on that. Then lift out the old pump, and put in the new one. Then put it all back together. Remember how the old pump was positioned when you pull it out and put the new one back in the same way.
