Disconnecting the fuel line from a Harley-Davidson motorcycle can be a tricky task. While there are many online forums and YouTube videos that offer advice and guidance on the process, it is important to approach the task with caution to avoid any potential damage or leaks. In some cases, it may be necessary to purchase a repair kit or replacement parts to ensure a secure and proper connection. Before disconnecting the fuel line, it is recommended to drain the fuel tank and relieve the pressure in the system. This can be done by opening the gas cap, removing the fuel pump fuse, and starting the bike to let it stall. Once the pressure is relieved, the fuel line can be safely disconnected.

What You'll Learn
Disconnecting the fuel line from the tank
Once the tank is drained, you can relieve the pressure in the fuel line. To do this, squeeze the tabs on the fuel line and remove it. You may need to push or depress buttons on the side of the fuel line to do this.
Now, you can disconnect the fuel line from the tank. The process may vary slightly depending on the model of your Harley touring bike, but the general steps are as follows:
- Remove the tank cover.
- Locate the silver cover under the tank cover and remove it. This should expose plugs, wires, and possibly some Torx screws.
- Once these are removed, you should be able to see inside the tank.
- Locate the tube quick connect on the pump, which should be on the passenger side of the bike.
- Disconnect the fuel line from the quick connect by lifting the sleeve, pulling the hose out, and then pulling the sleeve back down to prevent gas leaks.
It is important to note that you should replace the other hoses and filters while you have the tank open, especially if your bike has over 25,000 miles on it. Additionally, always refer to your Harley touring bike's service manual for specific instructions and safety precautions.

Disconnecting the fuel pump connector
Before beginning any work on your Harley touring bike, it is essential to refer to the official service manual for specific instructions and safety precautions. The following steps are intended as a general guide and may not cover all the necessary details for your specific model.
Firstly, locate the fuel pump fuse and remove it to relieve pressure in the fuel system. Open the gas cap to ensure that the pressure can be released safely. You can then start the bike and let it stall due to the lack of fuel. This step is crucial to avoid potential fuel spray or leakage, which could be hazardous.
Once the pressure is relieved, you can access the fuel pump connector. It is usually located near the fuel tank and may be covered by a panel or protective sleeve. Gently remove any coverings to expose the connector and the attached fuel lines. Some models may have tabs or buttons that need to be depressed to release the connector.
To disconnect the fuel pump, carefully squeeze or depress the tabs or buttons while gently pulling on the connector. Ensure you do not force it, as this could damage the connector or the surrounding components. If there are no tabs or buttons, refer to your service manual for the correct procedure, as some connectors may require specific tools or techniques for removal.
After successfully disconnecting the fuel pump, it is essential to control any residual fuel in the lines. Have a suitable container or drain pan ready to catch any fuel that may drip from the disconnected lines. If you need to drain the fuel tank, use a siphon pump to safely transfer the fuel to an approved storage container.
Finally, inspect the fuel pump connector and the surrounding area for any signs of damage or wear. Ensure that any O-rings or seals are in good condition and replace them if necessary. Refer to your service manual or seek advice from a Harley-Davidson authorised service centre if you notice any issues or if you require further guidance on reconnecting the fuel pump correctly.

Relieving the pressure
Disconnecting the fuel line from a Harley-Davidson motorcycle can be a tricky process, and it is important to relieve the pressure in the fuel line before attempting to do so. Here is a step-by-step guide to relieving the pressure:
- Open the gas cap to release any built-up pressure in the tank. This is a crucial first step to ensure that fuel does not spray out when the line is disconnected.
- Remove the fuel pump fuse. This will prevent the fuel pump from operating and reduce the risk of fuel leakage.
- Start the motorcycle and let it stall. With the fuel pump fuse removed, the bike will not be able to draw fuel, causing it to stall. This ensures that the fuel line is no longer under pressure.
- Squeeze the tabs on the fuel line connector. These tabs hold the fuel line in place, and by squeezing them, you can release the line. Be gentle but firm to avoid breaking the plastic components.
- Remove the fuel line. Once the tabs are squeezed, you can carefully pull the fuel line out of the connector. It may take some effort, but it should come out with a gentle tug. Ensure you are pulling in the correct direction, as per your motorcycle's manual.
By following these steps, you can safely relieve the pressure in the fuel line and proceed to disconnect it from your Harley-Davidson motorcycle. Always refer to your specific model's manual for additional instructions and safety precautions.

Disconnecting the quick connect at the tank
Firstly, it is crucial to relieve the pressure in the fuel system before disconnecting the fuel line. Open the gas cap and remove the fuel pump fuse. Then, attempt to start the bike a few times until it stalls, ensuring that there is no pressure left in the lines. This step is essential for safety and to prevent fuel spray and leaks.
Next, you will need to drain the fuel tank. This can be done by siphoning the fuel into a gas can or another suitable container. It is important to remove as much fuel as possible to minimize the risk of spills during the disconnection process.
Once the tank is drained, you can proceed to disconnect the quick connect. Lift the retainer sleeve, pull the hose out, and then pull the sleeve back down to prevent any remaining fuel from leaking out. Be gentle during this step to avoid damaging the plastic components.
If your quick connect is leaking, you may need to replace the O-rings. You can purchase a repair kit that includes new O-rings, and there are videos online that can guide you through the process. It is recommended to replace both sides of the valve, even if only one side appears to be the issue.
Finally, it is important to note that different models of Harley-Davidson motorcycles may have slight variations in the fuel system. Always refer to your specific model's service manual for detailed instructions and consult a professional if you are unsure about any steps.
By following these steps and taking the necessary precautions, you should be able to successfully disconnect the quick connect at the tank of your Harley-Davidson motorcycle.

Next, you will need to drain the fuel tank. You can use a cheap siphon pump to remove the fuel and avoid spills and messes. Alternatively, you can drain the fuel from the cross tube, but be aware that without disconnecting the other end, the fuel may spill out.
Once the tank is drained, you can proceed to disconnect the fuel line from the fuel rail. Refer to your Harley-Davidson service manual for specific instructions for your bike's model. As a general guide, you may need to push the fuel line towards the fuel rail, pull and hold the retainer sleeve, and then remove the fuel line. Be gentle to avoid damaging any plastic components.
If you encounter difficulties disconnecting the fuel line, there may be small buttons or tabs on the side that need to be depressed or squeezed before pulling the line out. Additionally, ensure that you are pulling the retainer sleeve in the correct direction, typically towards the primary side of the bike.
In some cases, you may need to remove the fuel tank to access the fuel rail and line properly. This process can vary depending on your Harley model, but it generally involves removing the tank cover and any plugs, wires, or screws holding the tank in place.
Finally, it is recommended to replace the fuel filter and hoses while you have the system disassembled. This proactive maintenance can help prevent future issues and ensure the optimal performance of your Harley touring bike.
