Work Area

Before starting work, ensure the engine is cool to reduce the chance of accidental ignition or burns. Work in a well-ventilated area to prevent exposure to harmful fumes. Avoid smoking or creating any sparks, as gasoline is highly flammable and can easily catch fire. Keep the area clear of any sources of ignition, such as lit candles or stoves.

Safe Handling

When handling the fuel lines, do not use your mouth to start a siphon; instead, use a pump or hose. Keep a fire extinguisher nearby in case of any accidents. Check that the fill valve is open, and stop transferring fuel before it reaches the top to avoid overfilling.

Maintenance

Regularly inspect and maintain the fuel lines to prevent issues. Check for any cracks, leaks, or signs of wear and replace damaged fuel lines immediately. Keep the fuel filter clean and replace it if necessary. Ensure the fuel tank is free of debris or sediment buildup, and store your Weedeater in a safe place, such as a well-ventilated shed, when not in use.

Spill Preparedness

Have spill response kits nearby in case of any fuel spills. Train yourself on how to respond to spills promptly and effectively. Keep the necessary absorbents and containment systems on hand to limit environmental harm.

Manufacturer's Instructions

Lastly, always refer to the manufacturer's instructions and guidelines for your specific Weedeater model. Following these recommended safety procedures will ensure your safety and the optimal performance of your equipment.

Removing the fuel lines

To remove the fuel lines from your Weedeater, you'll need to gather some tools and safety equipment. Ensure you have long-nosed pliers, a small screwdriver, wire cutters, a wire hook, and a receptacle for draining fuel. It is also important to wear protective gloves and safety glasses.

Once you have your equipment, follow these steps:

• Drain the fuel tank: Use the receptacle to drain any excess fuel from the tank. This is important for safety and to avoid spills.
• Disconnect the fuel lines from the carburetor: Use the long-nosed pliers to carefully detach the fuel lines from the carburetor.
• Cut the fuel lines: Take the wire cutters and cut the fuel lines as close to the fuel tank as possible.
• Press the remaining line into the tank: Utilise the small screwdriver to push any remaining portions of the fuel lines into the fuel tank.
• Remove the fuel cap: Unscrew and remove the cap from the fuel tank.
• Retrieve the lower halves of the fuel lines: Using the long-nosed pliers or the wire hook, carefully fish out the lower halves of the fuel lines from inside the fuel tank. One of these lines will contain the fuel filter.

By following these steps, you will successfully remove the old fuel lines from your Weedeater, preparing you for the next step of installing new ones. Remember to dispose of the old fuel lines properly and recycle any parts that can be recycled.

Installing the new fuel lines

To install the new fuel lines, follow these steps:

Firstly, inspect your specific tool to determine which line(s) to use. The fuel line kit contains two different sizes of the line to fit a variety of models. For some Weedeater blowers, you will only use the large fuel line for both the return and supply. Identify which line is which, and whether your model requires one or two lines.

Now, insert 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 fuel tank. Retrieve the fuel line from inside the tank using a wire hook. Cut away the tapered portion of the fuel line with wire cutters.

Next, install the fuel filter onto the end of the new line. Place the fuel filter and line back into the fuel tank, and use the wire hook to position the filter at the rear of the tank. Place the fuel line in its approximate position on the carburettor, and trim the excess line with wire cutters, leaving it slightly longer than needed.

For the return fuel line, cut a taper onto one end of the new line with wire cutters. Insert the tapered end into the second opening on the top of the fuel tank. Feed approximately two inches of the new line into the fuel tank. Place the return line in its approximate position on the carburettor, and trim the excess line with wire cutters, again leaving it slightly longer than needed.

Finally, connect the fuel lines to the carburettor. Place your finger over either of the ports on the carburettor and press and release the purge bulb. The intake port will draw your finger towards it, and the outgoing port will push your finger away. Determine whether the fuel lines require trimming, and trim to their final length if necessary. Install the fuel line containing the fuel filter onto the intake port, and install the return fuel line onto the outgoing port.

Reassembling the unit

Once you have installed the new fuel lines and filter, it is time to reassemble the unit. Here is a step-by-step guide to help you through the process:

• Reinstall the fuel cap: Place the fuel cap securely back onto the fuel tank. Ensure it is tightly sealed to prevent any fuel leakage.
• Connect the fuel lines to the carburetor: Identify the intake and outlet ports on the carburetor. The intake port will draw your finger towards it when priming, while the outgoing port will push your finger away. Connect the fuel line with the filter to the intake (incoming) port. Then, connect the return fuel line (without the filter) to the outgoing port.
• Trim the fuel lines: Check if the fuel lines require any additional trimming. Use wire cutters to trim the lines to their final length if needed. Ensure they are slightly longer than needed.
• Test for leaks and proper functioning: Before starting the engine, visually inspect the fuel lines for any signs of leaks or damage. Then, start the weedeater and observe the fuel lines under pressure. Also, conduct a practical test by running the weedeater and checking for any irregularities, such as engine sputtering or stalling. Ensure the fuel flow rate is consistent.
• Troubleshooting: If you encounter any issues, such as leaks or irregular performance, go back and double-check all the previous steps. Ensure that the fuel lines are correctly installed, securely connected, and free from kinks or twists. Check for any signs of damage, such as cracks or leaks, and replace the fuel lines if necessary. Also, ensure the fuel filter is clean and unclogged.
• Regular maintenance: Regularly inspect and maintain your weedeater's fuel system for optimal performance and longevity. Check the fuel lines for any wear and tear and replace them as needed. Clean or replace the fuel filter periodically to prevent clogs and maintain proper fuel flow. Additionally, remember to empty the fuel tank before storing your weedeater for prolonged periods.
• Safety precautions: Always prioritize safety when handling fuel lines. Work with a cool engine and in a well-ventilated area. Avoid smoking or creating sparks to prevent accidents and minimize risks. Wear protective gloves and safety glasses to safeguard against fuel contact or splashes. Lastly, consult your weedeater's manual for specific safety guidelines and instructions.
