To be absolutely sure, you might want to:
* Consult your owner's manual: This should have diagrams showing the fuel system.
* Use a repair manual: A Haynes or Chilton manual will have detailed diagrams and instructions.
* Look online: Search for "2002 Chevy S10 fuel line diagram" to find images. Be cautious using images alone as they may not be perfectly accurate for your exact model.
Important Safety Note: Working with fuel lines requires caution. Fuel is flammable and potentially explosive. Always disconnect the battery negative terminal before working near fuel lines. If you are uncomfortable working with fuel lines, it's best to take your vehicle to a qualified mechanic.
