Have you been able to find out any more about the '03 model fuel filter? I am only asking because my dealership suggested replacing it as part of regular maintenance... but I wanted to just buy the part and install it in my buddy's shop. So they sold me a filter and I also couldn't find the filter underneath the car. When I called the dealership, they said it's right by the fuel tank and they didn't mention anything about it being a part of the fuel pump/sender assembly. Would it be easy to replace if it's integral to the fuel pump or maybe the better question is: should I even bother with it?
