Jazzfest,
You can replace the pump without removing the tank. But, you do have to crawl under the front bumper to do it. Once under there just grab the pump and wiggle the sucker straight up and out. It will be stiff, but it will come out. Pull the electrical connection and tube to the washers, stick them on the new pump, and reverse the process to stick the new one back in.
Note that the pump mounts near the bottom of the tank. If the tank is full when you pull the pump you get wet.
Regards,
Randy
