Go under there and squirt some penetrating oil on the mounting bolts a couple of days in advance, this is good advice for anything you're planning to do. Start the car and remove the fuel pump relay under the hood, let it run until it stalls out. Remove the gas cap to relieve any pressure inside the tank. It's still going to be a sloppy job, but at least the gas will just run out, not shoot out under pressure. Lots of guys like to cut the rubber hoses and replace them as trying to wiggle them off often breaks the steel gas lines.
