To be certain, it's best to:
* Consult your owner's manual: This is the most reliable source.
* Check a repair manual specific to your 1987 Ford Ranger 2.9L: These manuals have detailed diagrams showing the location of all components.
* Use online resources: Websites like Ford forums or repair sites might have photos or diagrams showing the fuel filter location on similar models.
Be aware that working with fuel can be dangerous. Always take appropriate safety precautions, such as working in a well-ventilated area and wearing safety glasses.
