To find it definitively, you'll need to:
* Consult your owner's manual: This is the best resource for precise location information.
* Look under the car: Carefully inspect the frame rails near the fuel tank. The filter is usually a cylindrical canister, often metallic or with a metal canister. Look for fuel lines connected to it.
* Use a repair manual: A Haynes or Chilton repair manual for your specific year and model will have diagrams showing the fuel system and filter location.
Safety First: Always disconnect the negative battery terminal before working near the fuel system. Fuel is highly flammable.
