The 2000 Jeep Grand Cherokee Limited model has a complex vacuum system with numerous vacuum lines connected to various components. Unfortunately, I cannot provide a specific diagram of the vacuum lines for your vehicle. However, I can guide you on how to obtain this information.

To get a detailed diagram of the vacuum lines for your Grand Cherokee Limited, I recommend referring to the vehicle's service manual. The service manual contains comprehensive diagrams, schematics, and illustrations for all the systems in your Jeep, including the vacuum system. You can purchase a physical copy of the service manual from your Jeep dealership or look for a digital version online.

Additionally, you may find vacuum line diagrams in online forums, websites catering to Jeep enthusiasts, or by searching for Grand Cherokee repair manuals. Make sure to use diagrams that are specific to the 2000 Grand Cherokee Limited model to ensure accuracy.

Finally, if you are unable to locate a diagram through these methods, you can visually inspect the vacuum lines under the hood of your vehicle. Trace each line from its connection points to determine the routing and connections. Take pictures or notes to help you remember the layout before disconnecting any lines for maintenance or repairs.

Remember to handle the vacuum lines with care as they are crucial for proper engine performance and emissions control in your vehicle. If you are unsure about any aspect of the vacuum system, it is recommended to consult with a professional mechanic for assistance.
