Answer 2

This is from the GM service manual for your car. The tricky part is the quick disconnects. The plastic ones you can just squeeze. You need a tool for the metal ones. You can get it at most auto parts stores for about $10. Make sure you ask them how to use it as it's not obvious. It goes around the line and then you push it up into the fitting and pull the line apart. Good luck and don't forget to relieve the pressure. On yours you can hook up a fuel gauge to the valve under the hood and release the pressure that way. Another way is to disconnect the electrical connector for the pump at the tank and run the engine until it stops. I did a Grand Am yesterday which is very similar to your car and I had it off in about an hour. Try to clean up the threads on the strap bolts and use lots of WD-40 or PB Blaster. If you break them they are a major pain. Good Luck.
