Replacing Weedwacker Fuel Lines: A Step-By-Step Guide

If the fuel line on your weedwacker has broken, you can replace it yourself. First, remove the spark plug wire from the spark plug and pour the gas from the tank into a gas can. Remove the fuel lines from the carburetor using a pair of needle-nose pliers. If you can't pull the lines out, cut them flush with the tank and push the rest of the lines into the tank. Feed the new fuel lines into the tank, cutting the ends at an angle to make threading them easier. Push the larger vent line about an inch into the tank, and the smaller fuel supply line into the tank so that the fuel filter will lay on the bottom of the tank. Reattach the fuel filter, gas tank, fuel lines, and spark plug wire.

Disconnect the spark plug wire

Disconnecting the spark plug wire is an important step when replacing the fuel line of a weedwacker. Here is a detailed, step-by-step guide on how to do this safely and effectively:

Firstly, locate the spark plug wire. It is usually visible near the weedwacker's handle. Most models have a standard black wire and tubular boot, but some may have a rectangular rubber boot that covers both the wire and the plug. Once located, use a flat-head screwdriver to gently pry upwards and loosen the boot. This will ensure that you don't damage the boot or the plug if it is stuck. Pull the boot away from the plug when it unsnaps.

Next, fit the appropriate-sized socket over the plug. A 5/8-, 3/4-, or 13/16-inch socket may be needed, depending on the model of your weedwacker. Attach a 3/8-inch socket wrench, and possibly a 3-inch wrench extension if needed, to reach the plug. Now, use the wrench to loosen the plug by turning it sharply in a counterclockwise direction. Once it is loose enough, finish unscrewing it by hand.

Now that the spark plug is removed, it is important to plug the hole it leaves with a clean rag to prevent debris from falling into the combustion chamber. You should also wear rubber gloves when handling the plug, as your fingers will get greasy.

Finally, before proceeding with the rest of the fuel line replacement, it is a good idea to clean the area around the spark plug. Use a wire brush to clean any dirt or debris from around the plug, being careful not to let anything fall into the combustion chamber.

By following these steps, you can safely disconnect the spark plug wire on your weedwacker, allowing you to access and replace the fuel line.

Remove the fuel filter

To remove the fuel filter from your weedwacker, you will need to first locate the fuel filter inside the gas tank. It is a white cylinder attached to the end of the small fuel line. You can use a pair of needle-nosed pliers or a straightened wire coat hanger with a hook at the end to fish the filter out of the tank.

Once you have located the fuel filter, the next step is to remove it from the fuel line. This can be done by twisting and pulling the filter off the end of the line. If your fuel filter is inside the gas tank, you may need to remove the fuel line from the carburetor and pull it into the tank to access the filter.

If you are having trouble reaching the fuel filter with your tools, you can try making your own fuel line retriever by curving the end of a sturdy piece of wire into a hook shape. This can be inserted into the fuel tank to retrieve the line containing the fuel filter.

It is important to note that you should drain any excess fuel from the tank before attempting to remove the fuel filter. This will help ensure your safety during the removal process.

Disconnect the lines from the carburetor

Before disconnecting the lines from the carburetor, it is important to take a digital photograph or make a diagram of the fuel lines' configuration to the carburetor. This will be useful when it is time to reconnect the fuel lines.

To disconnect the lines from the carburetor, use a pair of needle-nose pliers to pull the fuel lines off of the carburetor.

It is important to note that before attempting to disconnect the fuel lines, you should disconnect the spark plug wire and drain the fuel tank in a well-ventilated area.

Pull the fuel lines out of the tank

Pulling the fuel lines out of the tank is a delicate process. Before you begin, ensure you have the right tools for the job. You will need a pair of needle-nose pliers, a funnel, and a gas can. Some sources also recommend having paper towels or shop rags, and a wire hanger.

First, disconnect the spark plug wire from the spark plug. Keep the wire at a distance so that it cannot make any contact with the spark plug. Next, pour the gas from the weedwacker's fuel tank into your gas can. Use a funnel to prevent spills. If any oil spills during this step, wipe it away with a cloth before continuing.

Now, you can begin to remove the fuel lines. Using your needle-nose pliers, pull the two fuel lines off the carburetor. If you are struggling to remove the lines, you may need to cut them flush with the tank. Then, use a small screwdriver to push the remaining line into the tank. Tip the weedwacker and shake it to ensure that all fuel line pieces have been removed from the tank.

If you are still unable to remove the fuel lines, you may need to remove the gas tank from the weedwacker. Locate the two screws on the gas tank and remove them. Then, carefully remove the gas tank and slowly pull out the two gas lines.

Once the fuel lines are out, discard the damaged line and replace it with a new one. Ensure that the new fuel line is compatible with your weedwacker model.

Feed the new fuel lines into the tank

To feed the new fuel lines into the tank, start by cutting the ends of the new lines at an angle. This makes them easier to thread into the tank. Next, force the cut ends of the lines into the correct holes in the tank, using needle-nose pliers if necessary. You may need to apply a small amount of oil to the outside of the lines if they are tight. Push the larger vent line about an inch into the tank, and push the smaller fuel supply line into the tank until the fuel filter is lying on the bottom of the tank.

If you are having trouble feeding the lines into the tank, you can try using a guide. Take a piece of small-diameter trimmer line or stiff wire about a foot long, and feed it through the hole from the bottom of the tank. Fish it out through the top of the tank where the fuel cap is, so that you have trimmer line sticking out of both ends. Then, feed the fuel line down from the top over the trimmer line until it pokes through the bottom. Grab the fuel line with a pair of needle-nose pliers and pull it through.
