To be certain, you should:
* Consult your owner's manual: This is the best resource for the exact location in your specific vehicle.
* Check online resources: Sites like Ford's parts website, or online forums dedicated to Ford Rangers (like Ranger-forums.com) might have diagrams or photos showing the canister's location.
* Look underneath the truck: Start near the fuel tank and carefully inspect the frame rails and surrounding area. The canister is usually a cylindrical container, often with hoses connected to it.
Caution: Be careful when looking under the vehicle. Make sure it's properly supported and you're working in a safe area.
