Replacing the fuel line on a small engine is a common task for small engine repair shops, and it is a skill that can be easily picked up by owners of small engines. The fuel line wears out over time due to exposure to elements like the sun, or simply due to age. The process of replacing a fuel line involves disconnecting the spark plug, removing the old fuel line clamps and hose, and installing a new fuel line of the correct length and size. This can be done using tools such as pliers, a utility knife, and scissors. The process may differ slightly depending on the model of the small engine and the type of fuel line.
How to Replace Fuel Line on Small Engine
| Characteristics | Values |

What You'll Learn
Disconnect the spark plug
Disconnecting the spark plug is a simple safety precaution when working on your small engine. It prevents the engine from accidentally turning on while you work on it, which could be dangerous. This step is optional, but it is highly recommended to avoid accidents that could cause injury.
To disconnect the spark plug, first locate the spark plug wire. Ensure you can access the boot of the spark plug wire. Do not pull the wire itself, as this could damage the wire and require an expensive replacement. Instead, grab the spark plug wire boot firmly and twist it in either direction, pulling it off simultaneously. This action will ensure that the wire breaks free if it is corroded. Twisting also allows for an easier disconnection from the top of the spark plug, reducing strain on the wire.
Once the spark plug wire is disconnected, it is a good idea to apply dielectric grease to the terminal on the top of the spark plug. This will prevent corrosion and sticking. To reconnect the spark plug wire, simply push it firmly back into place until you feel or hear a clip.
By taking the necessary precautions, you can ensure a safe and efficient process when working on your small engine.

Remove the old fuel line clamps
To remove the old fuel line clamps, you will need a pair of pliers. Grab the tabs on the fuel line clamp with the pliers and squeeze. Then, slide the fuel hose clamps off the fuel line where they are sitting on the connector. You may need to apply some force to do this, depending on the age of your fuel line. If the clamps are difficult to remove, you can try using a utility knife or scissors to slice through the fuel line first.
It is important to note that fuel lines and clamps wear out over time due to exposure to elements like the sun and ethanol. Therefore, it is recommended to replace the fuel line clamps along with the fuel line.
Additionally, as a safety precaution, it is advisable to disconnect the spark plug before beginning any work on the fuel line to prevent the engine from accidentally starting.
If you are unsure about the process or encounter any difficulties, it is best to consult a professional or seek advice from a reputable repair shop or mechanic.
By following these steps, you will be able to successfully remove the old fuel line clamps and prepare for installing the new fuel line and clamps in your small engine equipment.

Remove the old fuel line
To remove the old fuel line, start by disconnecting the spark plug. This is a safety precaution to prevent the engine from accidentally turning on while you work. Next, remove the old fuel line clamps by gripping the tabs with a pair of pliers and squeezing. Then, slide the fuel hose clamps off the connector. Now, pull the old fuel line off the connector. Depending on the age of the fuel line, you may need to apply some force. If it still won't come off, you can slice the fuel line with a utility knife.
It is important to note that some people have suggested using epoxy or electrical tape to patch up a fuel line. However, this is not recommended as it could be dangerous and turn into a "ball of fire". It is best to simply replace the fuel line with a new one.
When removing the old fuel line, be sure to drain all the gas into a safe container, such as a styrofoam cooler, before disposing of the old line.
If you are working on a two-cycle engine, there are a few additional steps. After disconnecting the spark plug and fuel lines from the carburetor, you may want to remove the fuel tank to make the job easier. Usually, this only requires removing a few screws. Once the tank is removed, take off the fuel tank cap. Reach into the fuel tank neck with a wire hook and grab the fuel tank vent and fuel filter. Pull them out through the fuel tank fill hole and cut them off with a utility knife or scissors.

Cut the new fuel line to length
When cutting the new fuel line to length, you can use your old fuel line as a guide. This will ensure that the new fuel line is the correct length and fits properly.
To cut the new fuel line, you can use a utility knife or a pair of scissors. Cut the fuel line to the desired length, making sure that it is straight and even.
It is important to choose the right tool for the job. A utility knife or scissors will provide a clean cut, which is important for the fuel line to function properly.
Additionally, you may want to consider cutting the end of the new fuel line into a point before feeding it through the fuel tank grommet. This will make it easier to insert the fuel line into the grommet. You can also wet the line with a small amount of lubricant to make it easier to install.

Install the new fuel line
To install the new fuel line, you will need to follow these steps:
Firstly, ensure you have the correct size of the fuel line for your small engine. The inner diameter of the fuel line is crucial to ensure a snug fit and prevent fuel leakage. If you are unsure, measure the old fuel line and compare it to the new one. It is recommended to have a slightly larger fuel line rather than a smaller one, as a smaller line can restrict fuel flow.
Now, cut the new fuel line to the correct length. You can use the old fuel line as a guide. If you are working with a two-cycle engine, you may want to cut the end of the new fuel line into a point to ease the installation process. Apply a small amount of lubricant to the end of the line before inserting it into the fuel tank grommet.
Next, feed the new fuel line through the fuel tank grommet. This can be a tricky process, so take your time. For two-cycle engines with small fuel tank grommets, you may need to use a wire hook or a piece of copper wire to guide the fuel line through. Insert the wire into the fuel line, loop and twist, and then carefully pull the fuel line through the grommet.
Once the new fuel line is in place, reinstall the fuel tank grommet into the fuel tank. Reattach the fuel tank, ensuring it is secure.
Finally, connect the fuel lines to the carburetor. Ensure all connections are secure and there are no leaks.
Your small engine should now be ready to use with its new fuel line.
