I changed my tank out today in just over an hour. You don't have to disconnect all of the hoses going through the firewall. Take the 3 hoses loose at the top of the tank. The hose that connects to the bottom of the the tank is about 4" long. Disconnect it from the steel line inside the engine compartment. I removed the spring clamp from underneath the car with a pair of long needle nose pliers. With that clamp off, and the hose loose, you can slide the tank back and remove the rear clamp, (connected to the port on the tank) from inside the trunk. Just reverse the steps and use screw clamps instead of spring clamps and the job is not too bad.
