Be cautious not to force any connections, as this can damage the wires or terminals. Ensure that you have a clear view of the connections to avoid any confusion during reassembly.

Remove the Harness (if necessary): If the wiring harness is difficult to access or needs to be removed for better access to the fuel pump, carefully detach it from the fuel pump and any other mounting points. Take note of the routing of the harness to ensure it can be reinstalled correctly.

Safety Precaution: When disconnecting the electrical connections, it's a good practice to ground the fuel pump to prevent any static electricity discharge, which could potentially damage sensitive electronic components. You can do this by temporarily grounding the fuel pump body with an insulated tool.

By following these steps, you'll ensure that the electrical connections are safely disconnected, allowing you to proceed with the removal of the fuel lines from the fuel pump of your 1999 Blazer without any electrical complications.

Release Clamps and Bolts: Loosen and remove any clamps or bolts securing the fuel lines to the pump

To begin the process of removing the fuel lines from the fuel pump of a 1999 Blazer, you must first locate the necessary components. The fuel lines are typically connected to the pump via clamps and bolts, so your initial task is to identify and access these fasteners. Start by inspecting the fuel pump assembly and locate the clamps or bolts that secure the fuel lines. These fasteners are usually found along the length of the fuel lines, where they connect to the pump.

Once you've identified the clamps or bolts, you'll need to loosen them. This step requires careful attention to avoid damaging the fuel lines or the pump. Use the appropriate tools for the job; a pair of adjustable wrenches or a socket set will be useful here. Loosen the clamps or bolts by turning them counterclockwise. You may need to apply significant force, especially if they have been tightened over time. Take your time and work steadily to ensure you don't overtighten the fasteners.

After loosening the clamps or bolts, you can now proceed to remove the fuel lines. Gently pull the lines away from the pump, being mindful of any residual fuel that may still be present. It's a good practice to have a container nearby to catch any spilled fuel, as this process can result in small amounts of fuel escaping. Take note of the positions of the fuel lines relative to the pump and the vehicle's body, as this information will be crucial for reinstallation.

Remember, the key to a successful fuel line removal is patience and a gentle approach. Avoid forcing the lines, as this can lead to damage. If you encounter any resistance, double-check that the clamps or bolts are fully loosened. Once the fuel lines are free, you can carefully set them aside, ensuring they remain tangle-free.
