What You'll Learn
Using a fuel pump
Firstly, you need to expose the fuel lines. To do this, pull up the rubber skirt found underneath your gas cap. Once you have access to the fuel lines, locate the fuel outlet line. You will need to pinch the blue tabs to remove it. Be cautious and careful when handling the tabs, as you do not want to cause any accidental damage. After removing the fuel outlet line, attach a suitable hose. Ensure that the hose fits snugly to avoid any leaks.
The next step is to find a suitable container to catch the fuel. This is important for safety reasons, as you do not want fuel spilling out. Place the container securely below the hose. Now, you can turn on the fuel pump. The pump will rapidly drain the fuel from the tank.
It is important to note that you may need to relieve the pressure in the fuel line after disconnecting it. You can do this by pushing the small valve inside the connector on the tank. Additionally, always be cautious of fire hazards when working with fuel. It is recommended to have a fire extinguisher nearby as a safety precaution.
Finally, once the tank is empty, be sure to disconnect the fuel pump. This is an important step to avoid any fuel leaks or spills.

Disconnecting the fuel hose
Locate the Fuel Lines: Begin by locating the fuel lines. Pull up the rubber skirt under your gas cap to expose the fuel lines. This is an important first step as it gives you access to the fuel system.
Identify the Fuel Out Line: Once the fuel lines are exposed, you need to identify the fuel out line. Look for the blue tabs on the fuel line. This is the line that allows fuel to exit the tank.
Pinch and Remove the Blue Tabs: Using your fingers, carefully pinch the blue tabs together. This action will allow you to remove the tabs and provide an opening for the next step.
Attach a Suitable Hose: Obtain a suitable hose that can be attached to the fuel out line. Ensure that the hose is fuel-safe and will not leak or cause any damage to the fuel system. Push one end of the hose securely onto the fuel out line.
Direct the Hose into a Proper Container: Take the other end of the hose and place it into an appropriate container designed to hold fuel, such as a fuel can or gas can. This step ensures that the fuel is drained and collected safely.
Depress the Button and Unplug the Hose: Some Harley models may have a button on the side of the hose. If your bike has this feature, depress the button and then carefully unplug the hose from the throttle body or tank bung.
Plug the Hose Back: After disconnecting the hose from the throttle body, plug it back into the tank bung. This step may vary depending on the specific model of your Harley Ultra Limited.
Locate and Remove the Fuel Pump Fuse: Find the fuel pump fuse, which is usually located near the fuel lines. Remove this fuse and keep it safe as you will need to reinstall it later.
By following these steps, you will have successfully disconnected the fuel hose and prepared your Harley Ultra Limited for further fuel drainage steps. Remember to exercise extreme caution when working with fuel, and always refer to the official service manual or seek professional guidance if you have any doubts.

Using a siphon
To drain the fuel tank on a Harley Ultra Limited motorcycle, one method is to use a siphon. This is a safe and effective way to remove the fuel without having to remove the tank itself. Here is a step-by-step guide on how to do it:
First, locate the fuel lines by pulling up the rubber skirt under the gas cap. Be careful when handling the fuel lines, as they can be delicate. Once you have located the fuel lines, identify the fuel outlet. This is where you will attach the siphon. Place a suitable container, such as a fuel can, below the outlet to collect the drained fuel. Ensure that the container is properly sealed and can hold the volume of fuel in the tank.
Next, obtain a siphon hose that is compatible with your Harley model. You can purchase a manual siphon pump from an auto parts store, or you may use a simple hose if you already have one. If using a hose, create a seal by attaching one end securely to the fuel outlet, then place the other end into the container. If you are using a manual siphon pump, follow the manufacturer's instructions to properly attach it to the fuel outlet and container.
Now, begin the siphoning process. If using a manual pump, follow the pump's instructions to activate it and start the flow of fuel. If using a hose, create a suction effect by mouth to start the flow, being careful not to ingest any fuel. Once the fuel is flowing, continue until the tank is empty or you have collected the desired amount.
During the siphoning process, be cautious and keep a close eye on the fuel levels in the tank and container. Ensure that the container does not overflow, as spilled fuel can pose a safety hazard. If you need to stop the flow of fuel temporarily, you can do so by pinching or clamping the hose.
Finally, once you have finished draining the fuel, carefully detach the siphon hose or pump from the fuel outlet and seal the fuel cap on the tank. Properly dispose of the drained fuel or store it in a safe location, away from open flames or heat sources.
Remember to exercise extreme caution when working with flammable liquids like gasoline. Always work in a well-ventilated area and avoid any potential sources of ignition. Have a fire extinguisher nearby in case of emergencies. By following these steps, you can safely and effectively drain the fuel tank on your Harley Ultra Limited using a siphon.

Fuel safety
When it comes to fuel safety, it is important to be aware of the potential fire hazards when draining a fuel tank on a Harley Ultra Limited. Keep all your fuel lines clean and be cautious of any spills or leaks. Ensure you have a proper container to catch the drained fuel and work in a well-ventilated area to avoid inhaling fumes.
One method to drain the fuel tank is to use a fuel pump. A portable 12v fuel pump can be used to empty the tank quickly and effectively. Ensure the pump is compatible with your bike and follow the manufacturer's instructions for safe use. Be careful not to run the pump for too long without fuel, as it may cause damage.
Another approach is to use a siphon hose to drain the fuel. This method may take longer but can be effective if done carefully. Locate the "Petcock" valve on the bottom of the tank and turn it off. Attach a "fuel-safe" hose to the valve and drain the fuel into a suitable container. Be cautious when handling the hose to avoid spills.
Additionally, consider using a product like "The Fuel Tool," which is designed to drain fuel tanks. While some may find it expensive, it can provide a safe and convenient option for draining fuel.
Remember, it is always important to refer to the official Harley Ultra Limited manual or seek advice from a qualified mechanic if you are unsure about any procedures. Your safety should be the top priority when working with flammable liquids like gasoline.

Removing the tank
First, ensure you have the necessary tools and safety precautions in place. Wear appropriate protective gear, such as gloves and eye protection, and have a fire extinguisher nearby. Place a container or drip pan underneath the tank to catch any fuel that may spill.
Next, locate the fuel lines and the fuel pump. Disconnect the fuel hose from the tank by depressing a button on the side of the hose and pulling it out. You may need to remove the seat and side cover to access the fuel pump and related components.
Once the hose is disconnected, carefully lift and remove the tank. The Harley Ultra Limited's tank can be heavy, especially if it's full, so consider having an extra pair of hands to help support the weight and avoid putting strain on the fuel pipe. Be cautious not to damage any hoses or components during this process.
If you're concerned about the weight of the tank and the potential strain on your back, you can opt to drain the fuel before removing the tank. This can be done by using a siphon hose, a manual siphon pump, or a portable 12v fuel pump to empty the tank. Remember to put the fuel cap on before removing the tank to avoid any spills.
Additionally, be mindful of any residual fuel that may be left in the system, especially if you're storing the bike indoors. The EFI system is under pressure, and while running the bike out of gas will remove most of the fuel, there may still be some remnants in the tank and carburetor. Ensure these are drained or emptied as well to mitigate any fire hazards.
By carefully following these steps, you can successfully remove the fuel tank on your Harley Ultra Limited.
