What You'll Learn
Disconnect the spark plug wire
Disconnecting the spark plug wire is an important safety step when working on your 4-cycle trimmer. Here is a detailed, step-by-step guide on how to do this:
First, locate the spark plug wire. It is usually found near the rear of the trimmer, connected to the spark plug. Before disconnecting the wire, ensure that the engine is cool and turned off. This is important for your safety as it prevents accidental starting.
Now, carefully pull the spark plug wire straight off the spark plug. It is important to pull the wire straight off to avoid damaging the connection or the wire itself. Once removed, set the spark plug wire aside in a safe place where it will not cause any obstruction or be at risk of damage.
With the spark plug wire disconnected, you can now safely proceed with the rest of the maintenance or repair work on your 4-cycle trimmer, such as replacing the fuel lines. Remember to refer to a repair guide or manual for your specific trimmer model when performing any maintenance or repairs.
After completing your work, remember to reconnect the spark plug wire to the spark plug before starting the engine. Ensure that the connection is secure and that the wire is not damaged before operating the trimmer.

Remove the fuel lines from the carburetor
Before removing the fuel lines from the carburetor, it is important to disconnect the spark plug wire to prevent accidental starting of the engine. This is a crucial safety step that must be performed before carrying out any maintenance or repair work on the trimmer.
Once the spark plug wire is disconnected, the next step is to locate the fuel tank and carburetor on the trimmer. The fuel lines connect the fuel tank to the carburetor, and they need to be carefully removed using needle-nose pliers or hemostat forceps. It is important to be gentle during this process to avoid damaging the fittings. If the fuel lines are tightly attached, an easy technique is to use a flat-head screwdriver. Place the screwdriver against the end of the fuel line and apply some pressure to push it off the fitting.
After removing the fuel lines from the carburetor, it is important to inspect the fittings for any signs of damage. If the fittings are damaged, they should be replaced before installing the new fuel lines. Additionally, it is recommended to clean the area around the carburetor and fuel tank to remove any dirt or debris that may have accumulated. This will help ensure that the new fuel lines are installed in a clean environment, reducing the risk of future issues.
Before installing the new fuel lines, it is crucial to refer to the diagram or digital photograph that was taken during the disassembly process. This will ensure that the new fuel lines are connected correctly to the carburetor. It is important to cut the new fuel lines to the proper length, ensuring a secure and leak-free connection. Once the new fuel lines are installed, the spark plug wire can be reconnected, and the fuel tank can be refilled with fresh fuel.
Finally, it is important to test the trimmer to ensure that the new fuel lines are working correctly. Start the engine and let it run for a few minutes, checking for any leaks or unusual noises. If there are no issues, the repair is complete, and the trimmer is ready to be used again.

Pull the fuel lines out of the tank
To pull the fuel lines out of the tank, you will need to have already disconnected the spark plug wire, emptied the fuel tank, and removed the fuel filter. You should also have a diagram or digital photograph of how the fuel lines are configured between the tank and the carburetor.
Now, pull the old fuel lines out of the tank. If necessary, use needle-nose pliers to grip the lines. If you can't pull the lines out, cut the lines flush with the tank, and then use a small screwdriver to push the rest of the lines into the tank. Tip the trimmer and shake any fuel line pieces out of the tank.
If the fuel line came apart while pulling it out, it’s a good idea to tip the trimmer and shake it to get all of the pieces out.

Feed the new fuel lines into the tank
To feed the new fuel lines into the tank, you will need to cut the ends of the new fuel lines at an angle to make it easier to thread them into the tank. Then, using a pair of needle-nose pliers if necessary, force the cut ends of the fuel lines into the proper holes of the tank. Make sure to push the larger vent line about an inch into the tank.
For the smaller fuel supply line, push it into the tank far enough so that the fuel filter will lay on the bottom of the tank. If the lines are too tight, apply a small amount of oil to the outside of the line. You can also use a lubricant like WD-40 to make it easier to pull the line through.

Reattach the fuel system
Now that you have installed the new fuel lines, it's time to reassemble the trimmer and reattach the fuel system. Here's a step-by-step guide:
- Reattach the fuel system: Position the fuel tank in its place and reinstall the fasteners that hold the carburettor mount plate in position.
- Reinstall the throttle cable: Thread the throttle cable through its hole in the mount plate and reattach it to the carburettor.
- Affix the carburettor: Reinstall the fasteners to secure the carburettor to the mount plate.
- Replace the fuel system cover: You may need to guide the carburettor's choke lever through an access opening. Replace all fasteners that hold the cover in position.
Your trimmer is now reassembled with new fuel lines installed. Be sure to consult your specific trimmer model's instructions for any additional steps or variations.
It is also recommended to refer to your diagram or notes one last time before reassembling the trimmer to ensure that you have correctly installed all the new fuel lines.
Finally, before using your trimmer, check for any fuel leaks and test it in a safe area to ensure it is functioning properly.
