To be certain, it's best to:
* Consult your owner's manual: This is the most reliable source for your specific vehicle.
* Look along the passenger-side frame rail: Start near the fuel tank and carefully examine the area for a cylindrical canister with fuel lines attached. It's often secured with clamps or straps.
* Use a repair manual: A Haynes or Chilton repair manual for your year and model will have diagrams showing the exact location.
Be cautious when searching near the fuel tank and fuel lines, as they may contain pressurized fuel.
