To be certain, it's best to:
* Consult your owner's manual: This is the most reliable source for the exact location.
* Use a repair manual or online diagrams: Sites like Haynes or Chilton offer repair manuals with diagrams showing the fuel filter location.
* Search online for images: Search for "2002 Chevy S10 fuel filter location" on Google Images to see pictures of the filter's location on similar vehicles.
Remember that working with the fuel system involves potential fire hazards. Take appropriate safety precautions, including disconnecting the battery's negative terminal before starting any work on the fuel system.
