What You'll Learn
How to disconnect AC and fuel lines on Ford vehicles
To disconnect the AC lines on a Ford Taurus, you will need a spring lock coupling tool set. The top line can be disconnected by pushing the tool into the "donut thing" from the firewall side and pulling the line outward. However, the lower line (condenser line) is known to get stuck often. To disconnect it, you can try heating the outside of the tube with a small propane torch or cigarette lighter for a minute or two to help break the grip of the O-ring that is keeping the lines stuck together.
Alternatively, you can try pressing the connection together, inserting the tool as hard as you can, and then pulling the hose off while still applying pressure to the tool. If you encounter a horseshoe-shaped retaining clip, you will need to remove it from the fuel lines. This type of removal tool has a hinged center section that fits around the fuel line.
To disconnect the fuel lines on Ford vehicles, you can use a special tool available from Ford and other manufacturers to remove the retaining clips, such as the Ford Tool T90T-9550-B or C or an equivalent. If you do not have access to the special clip tool, you can use a pair of narrow 6-inch slip-jaw pliers with a jaw width of 0.2 inches (5mm) or less. Align the jaws of the pliers with the openings of the fitting case and compress the part of the retaining clip that engages the case.
If the fuel line has a green tab, you can try depressing the green strip with a small screwdriver while pushing the line towards the pump. You may need to rotate the line slightly, and it may help to spray some plastic-safe lubricant to loosen it.

Using the tool to separate spring lock couplings
Next, you will need to apply some force. Pull the male and female coupling fittings apart, and then remove the tool from the now-separated spring and lock coupling. This step may require some extra force, and possibly an extra pair of hands, but it will ensure the successful separation of the fittings.
The tools are designed to be spring-loaded in the closed position, which is a useful feature as it helps to deflect any spray that occurs when the line is disconnected. This is an important safety measure to be aware of when using the tool.
Additionally, the tools often come in a set of four, with different sizes to accommodate various coupling sizes: 3/4 inch, 3/8 inch, 1/2 inch, and 5/8 inch. This versatility allows them to be used on a range of vehicles, including Ford and Chrysler models, and for multiple applications beyond just air conditioning lines, such as fuel lines, fuel filters, and fuel tank return lines.

The process for GM and Chrysler vehicles
The AC fuel line disconnect tool is used to separate fittings found on A/C, filters, transmission, and fuel tank disconnect lines and components. The process for GM and Chrysler vehicles is as follows:
First, ensure that you have the correct size tool for your vehicle. The AC fuel line disconnect tool comes in various sizes, including 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", and 7/8". Check that the size of the tool is compatible with the size of your vehicle's pipeline.
Next, relieve the pressure in the fuel line before attempting to disconnect it. This is an important safety precaution. Once the pressure is relieved, insert the disconnect tool into the locking mechanism of the quick disconnect coupler. The tool will get under the locking mechanism and release the inner lip.
After the spring (locking mechanism) has been released, pull on the line. You should hear a slight "click," indicating that the tool has successfully released the locking mechanism. At this point, you can easily pull off the filter.
It is important to note that the AC fuel line disconnect tool is designed to work on late-model GM and Chrysler vehicles. For GM vehicles, it is compatible with 1989 and newer models. For Chrysler vehicles, the compatibility depends on the specific model and year. Always refer to the product specifications and your vehicle's user manual before using any tools or attempting any repairs.

AC and fuel line tool set-up
Setting up your AC and fuel line tool kit is a straightforward process, but it requires careful attention to detail. Here is a step-by-step guide to help you set up your tool kit efficiently and effectively:
Firstly, ensure you have a suitable workspace that is clean, well-lit, and organised. This will make the setup process easier and help you keep track of all the components of your tool kit. Lay out all the tools and parts included in your kit, such as the release tools and fittings, on your workbench.
Your AC and fuel line tool kit will typically include multiple release tools and fittings of various sizes. Identify each component and familiarise yourself with their specific functions and applications. The tools are designed to easily disconnect air conditioning lines and quick-connect fuel lines, specifically targeting the spring lock coupling.
The release tools will come in different sizes, such as 5/16", 3/8", 1/2", 5/8", 3/4", and 7/8.". These sizes are compatible with different vehicle makes and models. For example, the 5/16" tool is designed to disengage the spring lock coupling on Ford radiator and transmission lines, while the 3/8", 1/2", 5/8", and 3/4" tools are suitable for Ford and Chrysler vehicles.
As you organise the tools and fittings, create a logical system that will make it easier to access and use the tools when needed. You could group the tools by size or intended use, ensuring they are readily accessible during AC and fuel line maintenance or repair tasks.
Finally, once you have identified, familiarised, and organised all the components of your AC and fuel line tool kit, it is a good idea to store them securely in a designated toolbox or container. This will keep your tools together and protect them from damage or misplacement.

Safety precautions when using the tool
Safety should always be a top priority when using an AC fuel line disconnect tool. Here are some essential safety precautions to follow when using this tool:
Work in a Well-Ventilated Area
Always work in a well-ventilated area to avoid inhaling any toxic fumes from the fuel lines. Fuel vapors are flammable and can pose a risk of ignition.
Wear Protective Gear
Don appropriate personal protective equipment (PPE), including gloves and safety goggles, to protect yourself from potential fuel exposure. Gloves will also provide a better grip and protect your hands from any sharp edges.
Turn Off the Engine
Before beginning any work, ensure that the engine is turned off and the keys are removed from the ignition. This is crucial for safety and to prevent any accidental startups while working on the fuel lines.
No Open Flames
Never use an open flame near the fuel lines or any fuel-related components. Keep sparks or potential ignition sources away from the work area. Fuel vapors are highly flammable, and any ignition source could lead to a fire or explosion.
Keep a Fire Extinguisher Nearby
Have a fire extinguisher readily accessible in case of emergencies. This will allow you to quickly respond to any potential fires that may occur during the disconnection process.
Manage Spilled Fuel
Be prepared for minor fuel spillage by having a container or absorbent material nearby to capture any drips or leaks. This will help prevent contamination of the environment and reduce the risk of a fire.
Select the Correct Tool Size
Use a fuel line disconnect tool that is the correct size for the specific fuel line you are working on. Utilizing an incorrectly sized tool can result in damage to the fuel line or an insecure disconnection.
Remember to always prioritize safety and follow manufacturer instructions when using an AC fuel line disconnect tool.
