To find a relevant diagram, I suggest these avenues:
* Repair Manual: A Haynes or Chilton repair manual specific to your 2002 Chevy Malibu 3.1L will have the most detailed diagrams and explanations of the fuel system, including the fuel pump's location and components.
* Online Repair Manuals: Sites like Mitchell1 (subscription required) or AllData (subscription required) offer detailed diagrams and repair information.
* Parts Catalogs: Online parts stores (like AutoZone, Advance Auto Parts, or Napa Auto Parts) allow you to search for your vehicle and often provide diagrams showing the fuel pump and its relationship to other components within the fuel tank. You might need to search for "fuel pump assembly" to find the relevant diagram.
* YouTube: Search YouTube for "2002 Chevy Malibu 3.1L fuel pump replacement." Many videos showing the replacement process will include visual representation of the fuel pump's location and connections.
Remember that the diagram you find will likely show the *fuel pump assembly* which includes the pump itself, the sending unit (fuel level sensor), and possibly other components within the fuel tank. Focusing your search on "fuel pump assembly" will yield better results.
