Leaf blowers are a handy tool to have around, but like any machine, they require maintenance and repair. One common issue with leaf blowers is fuel line problems. Fuel lines can harden and crack over time, leading to dangerous fuel leaks. Therefore, it is important to know how to replace them. This involves first draining the fuel tank and then removing the old fuel lines. The new fuel lines can then be installed, with the small line connecting to the fuel filter inside the tank, and the large line pushed into the tank through the mounting hole. It is important to ensure that the lines are snug, as they will shrink over time and cause leaks if they are not tight enough.

Fuel line kit installation
Installing a fuel line kit is a straightforward process, but it is important to follow the instructions carefully to ensure a safe and proper installation. This guide will walk you through the steps to install a fuel line kit for a leaf blower.
First, ensure you are working in a well-ventilated area. Remove the fuel cap and empty the fuel from the tank into an approved storage container. Disconnect the wire from the spark plug to ensure the blower cannot start accidentally. Next, remove the blower housing screws and pull off the left side housing. This will expose the fuel tank and fuel lines.
Now, you can begin removing the old fuel lines. Note the configuration of the small and large fuel lines on the carburetor so you can reconnect them correctly later. Use needle-nose pliers to remove the fuel filter from the end of the small fuel line, and then pull the small fuel line out of the tank through the mounting hole. Cut one end of the new large fuel line at an angle, and push it into the tank through the mounting hole. Grab the end of the large fuel line through the mouth opening with the needle-nose pliers and pull it through.
Push the small fuel line back into the tank through the mouth opening. Tug on the other end of the small fuel line until the filter rests on the bottom of the tank. Cut the small fuel line to the same length as the original. Attach the fuel filter to the small fuel line.
Finally, position the left side of the housing near the blower and thread the fuel lines through the hole in the housing near the carburetor. Push the housing back together, ensuring that the eyelet for the starter pull cord is properly positioned. Insert the thumb screw in the housing and rotate it until it catches the nut, then tighten it. Install the remaining housing screws and reconnect the spark plug wire.
Your fuel line kit installation is now complete! Always refer to the manufacturer's instructions and take appropriate safety precautions when performing any maintenance or repairs.

Replacing fuel lines
If your leaf blower won't start, it could be that a clogged or cracked fuel line isn't letting gas into the carburetor. Here is a step-by-step guide on how to replace the fuel lines:
Firstly, in a well-ventilated area, remove the fuel cap and empty the fuel from the fuel tank into an approved storage container. Then, to ensure that the leaf blower can’t start, disconnect the wire from the spark plug. Loosen the thumb screw on the front of the housing and pull the blower tube off. Remove the screws from the air filter cover and then remove the air filter cover. Remove the carburetor mounting screws. Pull out the air box and release it from the carburetor throttle and choke levers. Note the configuration of the small and large fuel lines on the carburetor so you can reconnect them correctly later.
Now, you can start to remove the fuel lines. The end of the small fuel line is connected to the fuel filter inside the tank. Use needle-nose pliers to fish the fuel filter out of the mouth of the tank. Remove the fuel filter from the end of the small fuel line. Pull the small fuel line out of the tank through the mounting hole. Push the large fuel line into the tank through the mounting hole and pull it out of the mouth of the tank. Cut one end of the large fuel line at an angle. Push the angled end into the tank through the mounting hole far enough that you can grab the end through the mouth opening with needle-nose pliers.
Next, push the small line back into the tank through the mouth opening. Tug the other end of the small fuel line until the filter rests on the bottom of the tank. Cut the small fuel line to the same length as the original small fuel line. Position the left side of the housing near the leaf blower and thread the fuel lines through the hole in the housing near the carburetor. Position the handle properly and push the housing back together, making sure the eyelet for the starter pull cord is properly positioned. Insert the thumb screw in the housing at the front of the blower and rotate the screw just until it catches the nut; don’t tighten it yet. Loosely install two other housing screws to keep the housing in place while you install the fan cover. Pry the tab on the fan cover spring out until it is in the loaded position. Snap the fan cover into the housing while holding the spring in the loaded position.
Finally, position the carburetor on the side of the engine and reinstall the mounting screws. Position the air filter cover over the carburetor and secure it with the mounting screws. Push the blower tube back on the front of the housing and tighten the thumb screw. Reattach the spark plug wire.
If the engine won't start after replacing the fuel lines, you may need to rebuild the carburetor.

How to identify fuel lines
To identify the fuel lines on a blower, you must first understand the function of the fuel lines and the components of the blower. The fuel lines are responsible for transporting fuel from the tank to the engine, where it can be combusted to generate power.
On a leaf blower, the fuel lines typically run from the fuel tank to the carburetor, which mixes air and fuel before supplying it to the engine. The carburetor can usually be found on the side of the engine and is connected to the fuel tank via the fuel lines.
To identify the fuel lines, follow these steps:
- Locate the fuel tank and the carburetor: The fuel tank is typically located at the base of the blower, while the carburetor is positioned on the side of the engine.
- Trace the fuel lines: Follow the path of the hoses from the fuel tank to the carburetor. There should be at least two fuel lines: one for fuel intake and one for ventilation.
- Identify the fuel intake line: The fuel intake line is connected to the fuel filter inside the tank. Use needle-nose pliers to carefully remove the fuel filter from the tank and identify the line that is attached to it. This is the fuel intake line.
- Identify the ventilation line: The second line is typically used for ventilation purposes. It enters the fuel tank but may not be connected to anything specific inside the tank.
- Verify the connections: To ensure you have identified the correct lines, you can perform a simple test. Push one of the lines onto the carburetor and pump the bulb. If fuel spits out of the other hole on the carburetor, you have correctly identified the fuel intake and ventilation lines.
By following these steps, you can confidently identify the fuel lines on your blower and understand their routing from the fuel tank to the carburetor.

Fuel line issues
Fuel lines on blowers are prone to a number of issues. One of the most common problems is that fuel lines will rot away. This can cause fuel to leak, and may mean that the blower won't start. Another issue is that fuel filters get clogged over time. Purge bulbs will also wear out, and may need to be replaced.
If the engine won't start, you may need to rebuild the carburetor. To do this, first, remove the fuel cap and empty the fuel from the tank into an approved storage container. Disconnect the wire from the spark plug to ensure the blower can't start. Loosen the thumb screw on the front of the housing and remove the blower tube. Remove the screws from the air filter cover, then remove the cover itself. Remove the carburetor mounting screws, and pull out the air box. Release the air box from the carburetor throttle and choke levers. Note the configuration of the small and large fuel lines on the carburetor, so that you can reconnect them correctly later. Then, remove the fuel lines.
When you are ready to replace the fuel lines, first, position the carburetor on the side of the engine and reinstall the mounting screws. Position the air filter cover over the carburetor and secure it with the mounting screws. Reconnect the fuel lines, then push the blower tube back on and tighten the thumb screw. Finally, reattach the spark plug wire.

Fuel line maintenance
Fuel lines deliver fuel from the tank to the engine, and their proper functioning is critical for the performance and safety of the machine. Fuel lines will degrade over time, with issues such as leaks, cracks, corrosion, or wear, which can lead to engine inefficiency or a complete shutdown. Therefore, regular maintenance and inspection are necessary to prevent unexpected failures.
Before performing any maintenance on a fuel line, it is important to ensure the engine is turned off and completely cooled down to prevent accidents or injuries. The fuel supply valve should also be shut off to prevent any fuel from flowing through the lines during maintenance, reducing the risk of spills or accidents.
The next step is to visually inspect the fuel lines for any damage, paying close attention to connections and joints. If any issues are identified, they should be addressed immediately by repairing or replacing the affected sections. It is also important to remove any accumulated dirt, debris, or sediment that might obstruct the fuel flow, using appropriate cleaning tools and materials to avoid contamination.
If the fuel system includes a fuel filter, it should be inspected and replaced according to the recommended maintenance schedule. Clogged filters can impede fuel flow and negatively impact the engine's performance.
After maintenance, it is a good idea to conduct a pressure or leak test to ensure the fuel line is intact and can handle the required fuel pressure. This step helps verify that the line is free from leaks and can maintain the necessary fuel flow.
For leaf blowers, the fuel line maintenance process may involve removing the fuel tank and carburetor to access the fuel lines. This requires disconnecting the spark plug wire and removing the blower housing screws. Once the fuel lines are accessible, they can be cleaned, inspected, and replaced if necessary, following the specific instructions for the blower model.
