• Use long-nosed pliers to disconnect the fuel lines from the carburetor.
• Cut the fuel lines flush with the fuel tank using wire cutters.
• Press the remaining portions of the fuel lines into the tank using a small screwdriver.

Step 3: Retrieve the Lower Halves of the Fuel Lines

• Using long-nosed pliers or a long wire hook, reach into the fuel tank to retrieve the lower halves of the fuel lines. One of these lines will contain the fuel filter.
• Be cautious when performing this step, as you don't want to damage the fuel tank or any other components.

Step 4: Clean the Tank

• Before installing new fuel lines, it is good practice to clean the fuel tank to remove any debris or residue that may have built up.
• Use a clean cloth or brush to wipe down the inside of the fuel tank. Ensure that any cleaning materials you use are non-abrasive and won't leave behind any fibres or residue.

Once you have completed these steps, your fuel tank should be drained and ready for the next steps in the fuel line replacement process. Remember always to put safety first when working with fuel and power tools.

Remove the fuel lines

To remove the fuel lines from your high-wheel weed eater, you will need a few tools, including long-nosed pliers, wire cutters, a small screwdriver, and a wire hook. Start by draining any excess fuel from the fuel tank to avoid spills during the removal process.

Next, use the long-nosed pliers to carefully disconnect the fuel lines from the carburetor. Cut the fuel lines flush with the fuel tank using the wire cutters. Then, use the small screwdriver to gently press the remaining portions of the fuel lines into the fuel tank. Remove the fuel cap and use the long-nosed pliers or wire hook to retrieve the lower halves of the fuel lines, including the fuel filter, from inside the tank.

It is important to note that there are typically two fuel lines: one with the fuel filter and one with a white plastic adapter or a return line. Be sure to take note of their routing and any attached fittings or filters before removing them completely. Additionally, pay attention to the length of the lines inside the tank and make sure to follow the specific instructions for your weed eater model.

By following these steps, you can safely and effectively remove the fuel lines from your high-wheel weed eater, preparing you for the next step of installing new fuel lines.

Install the fuel line

To install the fuel line, you will need a new fuel line kit that is compatible with your specific weed eater model. The kit will include two different sizes of the line, so you can choose the one that fits your tool.

Begin by inserting the tapered end of the new fuel line into one of the openings on the top of the fuel tank. Feed approximately six inches of the new line into the tank. Use a wire hook to retrieve the fuel line from inside the tank through the filler neck. Cut away the tapered portion of the fuel line using wire cutters.

Now, install the fuel filter onto the end of the new line. Place the fuel filter back into the fuel tank, using the wire hook to position it at the rear. Take the fuel line and place it in its approximate position on the carburetor. Trim the excess line with wire cutters, leaving it slightly longer than needed.

Next, cut a taper onto one end of the new return fuel line using wire cutters. Insert this tapered end into the second opening on the top of the fuel tank. Feed approximately two inches of the new line into the tank. Place the return line in its approximate position on the carburetor and trim any excess.

Finally, connect the fuel lines to the carburetor. Place your finger over either of the ports on the carburetor and press and release the purge bulb. The intake port will draw your finger towards it, while the outgoing port will push your finger away. Determine if the fuel lines require additional trimming and adjust accordingly. Install the fuel line with the fuel filter onto the intake port and the return fuel line onto the outgoing port.

Once the fuel lines are connected, you can reassemble the unit by reinstalling the fuel cap onto the tank.

Install the return line

Now that you have removed the old fuel lines and are ready to install the new ones, here is a detailed, step-by-step guide on installing the return line of your high-wheel weed eater:

Step 1: Cut the new return line to size

Use wire cutters to cut a taper at one end of the new return fuel line. Ensure that the cut end has an extreme angle, as this will make it easier to feed the line through the openings.

Step 2: Feed the return line into the fuel tank

Insert the tapered end of the new return line into the second opening on the top of the fuel tank. Gently feed approximately two inches of the new line into the tank. Be careful not to bend or damage the line during this process.

Step 3: Position the return line

Place the return line in its approximate position on the carburetor. Use wire cutters to trim the excess line, leaving it slightly longer than needed. This will ensure a proper fit and connection.

Step 4: Connect the return line to the carburetor

Identify the outgoing port on the carburetor. You can do this by placing your finger over either of the ports and pressing and releasing the purge bulb. The outgoing port will push or blow your finger away. Install the return line (the line without the fuel filter) onto this outgoing port. Ensure that the connection is secure and tight.

Step 5: Reassemble the unit

After you have installed both the supply and return lines, it is now time to reassemble the fuel cap and any other components you removed during the process. Securely tighten the fuel cap onto the fuel tank.

By following these steps, you will have successfully installed the return line on your high-wheel weed eater, ensuring a proper fuel flow and engine performance. Always remember to refer to your specific model's manual for any additional instructions or variations.

Connect the fuel lines to the carburetor

Now that you have removed the old fuel lines and are ready to install the new ones, here is a detailed, step-by-step guide on connecting the fuel lines to the carburetor of your high-wheel weed eater:

Before beginning, ensure you have the correct size and type of fuel lines for your weed eater model. It is best to use fuel lines specifically designed for weed eaters as they are made to withstand the harsh conditions and chemicals associated with fuel.

Step 1: Identifying the Carburetor

The carburetor is responsible for mixing air and fuel before it enters the engine. It is usually located near the engine and has two ports: an intake (incoming) port and an outgoing port. The intake port will draw your finger towards it when you press and release (prime) the purge bulb, while the outgoing port will push your finger away.

Step 2: Trimming the Fuel Lines

Before connecting the fuel lines to the carburetor, ensure they are trimmed to the correct length. Use wire cutters to trim the excess line slightly longer than needed. The fuel line with the filter attached should be connected to the intake port, while the return fuel line (without the filter) should be connected to the outgoing port.

Step 3: Connecting the Fuel Lines

Now, it's time to connect the fuel lines to the carburetor. Insert the fuel line with the filter into the intake (incoming) port on the carburetor. Then, connect the return fuel line to the outgoing port. Ensure that the connections are secure and tight.

Step 4: Final Checks

Once the fuel lines are connected, check for any leaks. Turn on the engine and let it run for a few minutes. If there are no leaks, your weed eater is ready to use. If you notice any leaks, tighten the connections and check again.

By following these steps, you can ensure that your weed eater's fuel lines are properly connected to the carburetor, allowing for a steady flow of fuel and efficient operation of your machine.
