Cleaning it makes more sense than replacing, and you don't need to run any magic juice through the tank. It's not hard to remove. The tank needs to be drained, but it doesn't have to come out. Lift the car, and look up beside the left rear wheel. You'll se a rubber seal with a few lines running through it. Pull the rubber down, and you'll see the tank connection. The rubber hose screws into the strainer. Undo the hose, then a big socket is all you need to remove the filter. It can be washed with dishwashing liquid and replaced. Just let it dry before you put it back, and use an new o-ring if the old one is deteriorated.
