To find it definitively, I recommend:
* Consulting your owner's manual: This is the best resource. It should have a diagram showing the location.
* Looking at a repair manual for your specific year and model: A Haynes or Chilton manual will have detailed diagrams and instructions.
* Searching online for a parts diagram: Many auto parts websites allow you to search by year, make, and model, and will show a parts diagram that includes the fuel filter.
Because you're working with fuel, be very careful. Turn the ignition off, and disconnect the negative battery terminal before attempting to locate or replace the fuel filter. Fuel is flammable and under pressure.
