What is the Lisle 37000 Disconnect Tool?

The Lisle 37000 is a set of six durable, color-coded disconnect tools that work with different sizes of quick-connect fittings commonly found in fuel and air conditioning lines. Each tool is designed to slide into the quick-connect fitting, releasing the connection without causing damage to the line or fitting.

Step 1: Identify the Line Size

Before using the tool, you need to identify the size of the line you’re working on. The Lisle 37000 kit comes with tools for six different sizes, typically ranging from 5/16” to 7/8”. The correct size is crucial to ensure the tool fits properly and disconnects the line effectively.

• 5/16” (Blue)
• 3/8” (Red)
• 1/2” (Black)
• 5/8” (Gold)
• 3/4” (Green)
• 7/8” (Silver)

Step 2: Select the Appropriate Tool

Once you’ve determined the size of the line, select the corresponding tool from the kit. Each tool is color-coded for easy identification. Make sure the tool size matches the line size to avoid any damage or difficulties during the disconnection process.

Step 3: Position the Tool

With the appropriate tool in hand, slide it over the fuel or air conditioning line until it reaches the quick-connect fitting. The tool’s design allows it to slip between the line and the fitting, pressing against the retaining clip inside the fitting.

Step 4: Disconnect the Line

Once the tool is in place, apply firm pressure and push the tool into the fitting while simultaneously pulling the line away from the fitting. The tool will release the retaining clip, allowing the line to disconnect. It’s essential to apply even pressure to avoid bending or damaging the line or fitting.

Step 5: Inspect and Store the Tool

After disconnecting the line, inspect both the tool and the fitting to ensure there’s no damage. If everything looks good, clean the tool and store it back in its case. Proper maintenance will prolong the tool’s life and ensure it’s ready for the next use.

Tips for Using the Lisle 37000 Disconnect Tool

• Ensure a proper fit: Double-check the line size before selecting the tool to avoid using the wrong size, which can damage the line or fitting.
• Use even pressure: When disconnecting the line, apply even pressure to prevent bending or damaging the tool or line.
• Practice on scrap parts: If you’re new to using the Lisle 37000, practicing on a scrap part can help you get comfortable with the process before working on your vehicle.
