I want to pass along some information I've gathered during my recent fuel pump replacement on my wife's 05 which is a non-turbo. There is a filter attached to the bottom of the fuel pump, many of us call this a "fuel sock". There is no other fuel filter in this car. There is a connector, located on the firewall almost directly in front of the glove box, that is easily disconnected to confirm if your getting fuel from the pump. Be sure to have a rag there when you key the ignition to ON which activates the fuel pump. This location is also the most convenient place to test fuel pressure. The spec is 58lbs.
