The fuel lines on this vehicle are typically located beneath the dashboard and along the firewall, running towards the fuel tank and engine bay.

To begin, locate the fuel tank, which is usually positioned at the rear of the vehicle, just above the spare tire. From there, trace the fuel lines that run from the tank towards the engine compartment. These lines are often made of rubber and can be quite long, so it's important to identify the correct ones. Look for any distinctive markings or colors on the lines, as these can help you differentiate them from other hoses.

Once you've identified the fuel lines, it's a good idea to mark them for easy removal. You can use a permanent marker or a piece of tape to label each line. For example, you could label one line as "Fuel Line A" and another as "Fuel Line B," making it clear which lines are connected to the fuel pump, injectors, or other components. This simple step will save you time and frustration when it's time to remove the lines, as you won't have to trace and identify them again.

Additionally, take note of any clips or brackets that secure the fuel lines in place. These small fasteners are often overlooked but are crucial for a successful removal process. Carefully inspect the lines and their attachments, ensuring you understand the layout and how each component is connected.

By taking the time to locate and mark the fuel lines, you'll make the entire removal process smoother and less prone to errors. This step is often overlooked but is an essential part of any successful automotive repair or maintenance task. Remember, proper identification and preparation are key to ensuring a job well done.

Tools Needed: Gather necessary tools like a fuel line cutter or pliers

To begin the process of removing the fuel lines on a 1999 Chevrolet Envoy, it is crucial to have the right tools at hand. The primary tool you will need is a fuel line cutter, which is specifically designed to cut through fuel lines without causing damage to the surrounding components. These cutters are typically made of durable materials and can handle the high pressure associated with fuel lines. Additionally, having a set of pliers is essential for gripping and manipulating the fuel lines during the removal process.

For the fuel line cutter, look for a model that is compatible with the size of the fuel lines on your Envoy. Different vehicles may have varying fuel line diameters, so ensure you have the appropriate cutter for your specific needs. These cutters often feature a sharp blade or a cutting wheel that can efficiently sever the fuel lines. It is important to use this tool carefully to avoid any accidental cuts or punctures.

Along with the cutter, a set of adjustable pliers will be invaluable. These pliers provide versatility as they can adjust to different sizes and shapes of fuel lines. The jaws of the pliers should be sturdy and capable of exerting enough force to grip the fuel lines firmly. Having a pair of pliers with a serrated edge can also help in gripping the fuel lines more effectively, especially if they are corroded or damaged.

Other tools that might be useful include a fuel line primer or cleaner to ensure a clean and dry fuel line during installation. Additionally, having a fuel line adapter or a temporary fuel line setup can be helpful for testing or temporary repairs.
