If you're looking to push a fuel line through a leaf blower's fuel tank, it's likely that you need to replace the fuel lines. This could be because the engine won't start, the gas has gone stale, or the fuel lines have rotted, cracked, or dissolved. Before you begin, it's important to note that repairing appliances can be hazardous, so ensure you use the proper tools and safety equipment, and follow all instructions. Now, to push the fuel line through, you'll need to remove the fuel tank and the old fuel lines, and then feed the new lines through the tank and housing. You may need to cut the fuel lines at an angle to help guide them through, and you can use a wire or fishing line to help feed the lines through. Once the new lines are in place, you can reattach the fuel tank and any other components you removed, being sure to follow the correct procedure to avoid leaks or damage.

What You'll Learn
Removing the fuel tank
Step 1: Prepare the Work Area
Before beginning any repair work on your leaf blower, it is essential to prioritize safety. Ensure you are working in a well-ventilated area to prevent the buildup of hazardous fumes. Place the leaf blower on a flat, stable surface, and have all the necessary tools within easy reach.
Step 2: Drain the Fuel Tank
Remove the fuel cap and carefully drain the fuel from the tank into an approved storage container. This step is crucial, as it reduces the risk of fuel spillage or leakage during the removal process. It also ensures that you are working with a dry tank, making it safer to handle.
Step 3: Disconnect the Spark Plug
To guarantee that the leaf blower cannot accidentally start during the repair process, disconnect the wire from the spark plug. This step is often accompanied by a visual confirmation, such as a photo, to ensure the correct procedure is followed.
Step 4: Remove Housing Screws
Using the appropriate screwdriver, remove the right-side blower housing screws. This will allow you to access the internal components of the leaf blower, including the fuel tank and fuel lines. Keep the removed screws in a safe place to avoid misplacing them.
Step 5: Accessing the Fuel Tank
With the housing screws removed, gently pull off the left-side housing. This will expose the fuel tank and provide the necessary access for its removal. Depending on the model of your leaf blower, you may need to remove additional components, such as the air filter cover, to fully access the fuel tank.
Step 6: Detach the Fuel Lines
Before removing the fuel tank, you must carefully detach the fuel lines that connect to it. Use needle-nose pliers to carefully remove the fuel filter from the mouth of the tank. Once the fuel filter is detached, gently pull the small fuel line out of the tank through the mounting hole. Take note of the configuration of the fuel lines to ensure proper reassembly.
Step 7: Lift Out the Fuel Tank
With the fuel lines detached, you can now carefully lift out the fuel tank. Depending on the model of your leaf blower, there may be additional steps or securing mechanisms that need to be addressed. It is important to refer to your leaf blower's manual or seek guidance from online resources specific to your model if you encounter any deviations from the standard process.

Using pliers to remove the fuel filter
Pliers are an essential tool when it comes to removing the fuel filter from a leaf blower. The process can be delicate, so it is important to follow the correct steps to ensure you do not damage any other components.
Firstly, you will need to prepare the leaf blower for maintenance. Ensure the engine is cool if it has been recently used, and drain the fuel tank. You should also disconnect the wire from the spark plug to ensure the leaf blower cannot start during the process.
Now, you can begin to access the fuel filter. Remove the right-side blower housing screws, and pull off the left-side housing. Then, remove the fuel tank. The fuel filter is connected to the end of the small fuel line inside the tank. Using a pair of needle-nose pliers, carefully fish the fuel filter out through the mouth of the tank. Once you have a firm grip on the filter with the pliers, gently twist and pull to remove it from the end of the small fuel line.
At this point, you can choose to clean or replace the fuel filter. If you are simply cleaning it, you may need to use the pliers again to slide the retaining spring away from the filter. However, if you are replacing the filter, you can dispose of the old one, and prepare the new fuel line with a new filter attached.

Pushing the large fuel line into the tank
Firstly, it is important to understand the function of the fuel lines in a leaf blower. The large fuel line is typically connected to the fuel filter, extending deep into the tank. It supplies fuel to the carburetor, ensuring the engine receives the necessary fuel for operation.
Now, to push the large fuel line into the tank, begin by removing the fuel tank from the leaf blower. This will provide you with access to the tank and the necessary space to work. Once the fuel tank is removed, identify the mounting hole, which is where the fuel line will be inserted. Cut the end of the new large fuel line at a thin angle, as this will make it easier to feed into the tank.
Next, you can use a thin, stiff wire, such as a large paper clip, or fishing line. Bend the wire so that it feeds towards the fuel cap, and then slide the fuel line over the wire. Work it carefully until the tip of the fuel line reaches the hole. At this point, you can use needle-nose pliers to grasp the tip of the fuel line and pull it through the mounting hole, ensuring it exits through the mouth of the tank.
Finally, you will want to position the fuel filter correctly. Pull on the large fuel line from the mouth of the tank until the filter rests at the desired position within the tank. This process ensures the fuel filter is securely placed and can effectively filter the fuel being drawn into the carburetor.

Trimming the fuel line
Firstly, it is important to understand the configuration of the fuel lines. The fuel lines consist of a small line and a large line. The small line is connected to the fuel filter inside the tank, while the large line is pushed into the tank through the mounting hole.
When trimming the fuel line, the goal is to ensure that the lines are snugly fit to prevent leaks. Here are the steps to achieve that:
- Cut the end of the new fuel line at a thin angle. This angled cut will help guide the fuel line through the mounting hole. Use sharp scissors or a utility knife to make a clean cut.
- Determine the approximate position of the fuel line on the carburetor. Place the fuel line in this position, ensuring it is slightly longer than needed.
- Use wire cutters to carefully trim the excess fuel line. Take your time and cut only small sections at a time to avoid overcutting.
- Check if the fuel line requires additional trimming. If needed, use the wire cutters again to trim the line to its final length. Ensure that the length of the new fuel line matches the original fuel line to guarantee a secure fit.
- Once the fuel line is trimmed to the appropriate length, it can be securely placed back into the fuel tank through the mouth opening.
By following these steps and paying attention to detail, you will successfully trim the fuel line for your leaf blower, ensuring a snug fit that prevents leaks and contributes to the overall efficiency of the machine.

Reattaching the spark plug wire
Firstly, locate the spark plug wire and carefully unplug it from the spark plug. This is important for safety, as it ensures the leaf blower cannot start while you are working on it. It is also a good idea to clean any dirt or debris from the spark plug to ensure a good connection when you reattach the wire.
Next, you will need to check the spark plug gap. This refers to the distance between the centre and ground electrodes, and it is crucial for ensuring proper ignition and combustion within the engine. Use a gapping tool to carefully adjust the gap to the manufacturer's recommended specifications, which typically range from 0.020 to 0.030 inches.
Once you have adjusted the gap, you can reattach the spark plug wire securely onto the spark plug. Make sure it is snug but not overly tight.
Finally, start up your leaf blower and listen for any unusual sounds or performance issues. If everything sounds normal and the leaf blower is running smoothly, you have successfully reattached the spark plug wire and adjusted the spark plug gap.
