Replacing Fuel Line On Weedeater Trimmer: Step-By-Step Guide

If you're a homeowner or a professional landscaper, you know the importance of keeping your tools in good working condition. A weed eater trimmer is a versatile tool for maintaining your lawn and getting rid of weeds, but like any machine, it may require maintenance and repairs from time to time. One common issue is fuel line damage or wear, which can hinder the trimmer's performance and efficiency. In this guide, we will cover everything you need to know about replacing the fuel lines on your weed eater trimmer, from gathering the necessary tools and materials to step-by-step instructions on installing the new fuel lines and testing them. By following these simple steps, you'll be able to tackle this repair yourself and get your trimmer running like new again.

Disconnect the spark plug wire

Disconnecting the spark plug wire is one of the first steps in repairing a Weed Eater Trimmer. Here is a detailed, step-by-step guide on how to do this:

Firstly, locate the crankcase, which is a protective plate that covers the spark plug. It should be easy to lift with your fingernail. Use your nail to gently lift the cover and reveal the spark plug and spark plug wire.

Next, you will need to identify the boot protector, which is a small rubber cap that fits over the spark plug to protect it from debris and contaminants. It could be rectangular or tubular in shape. Identify the spark plug wire, which is attached to the boot protector.

If the boot protector seems stuck to the spark plug, do not tug on it forcefully. Instead, use a flat-head screwdriver to gently pry upwards on the boot protector while simultaneously pulling it off with your other hand. You can also try wiggling it gently from side to side to loosen its grip on the plug.

Once the boot protector is removed, you can now access the spark plug. Apply the spark plug socket over the top of the spark plug. Most weed eaters use a 5/8-inch socket, but some models may require a 3/4-inch or 13/16-inch socket instead. So, ensure you have the correct socket size for your specific trimmer model.

Now, attach the socket wrench and turn it counterclockwise to loosen the spark plug. Once it starts turning easily, you can switch to using your fingers to continue turning it. Carefully lift the spark plug out, and you have successfully disconnected the spark plug wire.

It is important to note that you should always pull on the spark plug itself and never on the spark plug wire when removing it. Additionally, remember to clean the surrounding areas of any dirt and debris as you work.

Remove the fuel filter

To remove the fuel filter from your weed eater trimmer, you'll first need to locate it inside the gas tank. The fuel filter is a white cylinder attached to the end of the small fuel line. Use a pair of needle-nosed pliers or a straightened wire clothing hanger with a hook at the end to fish it out of the tank. Once you've got a hold of it, simply pull the fuel filter off the end of the fuel line.

If your fuel filter is held in place by a retaining ring, you'll need to remove this first. The retaining ring can usually be easily removed with a screwdriver. With the retaining ring out of the way, you can then remove the fuel filter line. Instead of trying to pull the line through the fuel tank hole, it's much easier to cut the line with a pair of flush-cut diagonals or similar cutters and push the old fuel filter into the tank.

Now that the fuel filter is out of the way, you can focus on removing the rest of the fuel lines. Start by disconnecting the lines from the carburetor using your needle-nose pliers. It's important to make a diagram or take a picture of how the fuel lines are configured between the tank and the carburetor so that you can reconnect them correctly later. Once the lines are disconnected, pull them out of the tank. If they're difficult to remove, you can cut them flush with the tank and use a small screwdriver to push the remaining lengths into the tank.

With the fuel filter and fuel lines removed, you can now install a new fuel filter and fuel lines. Cut the ends of the new fuel lines at an angle to make them easier to thread into the tank. Use needle-nose pliers if necessary to force the cut ends of the fuel lines into the proper holes in the tank. Push the larger vent line about an inch into the tank, and the smaller fuel supply line in far enough so that the new fuel filter will lay on the bottom of the tank.

Finally, reconnect the fuel lines to the carburetor, referring to your diagram or digital photograph to ensure you connect them correctly.

Disconnect the lines from the carburetor

Disconnecting the fuel lines from the carburetor is a crucial step in replacing the fuel lines on your weed eater trimmer. Here is a detailed, step-by-step guide to help you through the process:

Make a Diagram or Take a Picture: Before you start, it is important to understand the configuration of the fuel lines. Make a diagram or take a picture of how the fuel lines are routed between the fuel tank and the carburetor. This will serve as a reference when reconnecting the new fuel lines.

Gather the Necessary Tools: You will need a pair of needle-nose pliers or a similar tool to carefully grip the fuel lines without causing damage.

Disconnect the Lines: Using the needle-nose pliers, gently grasp the fuel lines where they connect to the carburetor. Slowly and carefully, pull the fuel lines away from the carburetor fittings. It is important to do this slowly and with control to avoid any sudden movements that could lead to spills or damage.

Release the Clamps: In some cases, the fuel lines may be secured to the carburetor with clamps or fittings. If so, use the appropriate tool, such as a small screwdriver, to carefully release these clamps before attempting to remove the fuel lines.

Catch Any Spills: Have a container or towel ready to catch any fuel that may spill during the disconnection process. This will help prevent fuel from coming into contact with your skin or the surrounding area.

Note the Routing: Once the fuel lines are disconnected, take note of their routing and any fittings or filters attached to them. This information will be useful when installing the new fuel lines to ensure they are routed correctly.

By following these steps, you can successfully disconnect the fuel lines from the carburetor of your weed eater trimmer. Remember to work slowly and carefully to avoid any spills or damage to the fuel lines or carburetor. Always refer to your specific trimmer's manual for additional instructions or variations that may be unique to your model.

Pull the fuel lines out of the tank

Pulling the fuel lines out of the tank is a crucial step in replacing the fuel lines of your weed eater trimmer. Here is a detailed, step-by-step guide to help you through the process:

Disconnect the Spark Plug Wire: Before beginning any work on your weed eater trimmer, it is essential to disconnect the spark plug wire to prevent accidental starting. This safety measure ensures that the engine does not turn on unexpectedly during the maintenance process.

Remove the Fuel Filter: Locate the fuel filter inside the gas tank. It is usually a white cylinder attached to the end of the small fuel line. Carefully fish out the filter using a pair of needle-nosed pliers or a straightened wire hanger with a hooked end. Once the filter is accessible, gently pull it off the end of the fuel line.

Make a Diagram: Before proceeding, it is highly recommended to make a diagram or take a picture of how the fuel lines are configured between the tank and the carburetor. This will serve as a reference when reconnecting the new fuel lines, ensuring that they are installed correctly.

Pull Out the Old Fuel Lines: Now, it's time to remove the old fuel lines from the tank. Grip the lines with needle-nose pliers and pull them out gently. If the lines are difficult to remove, you may need to cut them flush with the tank and then use a small screwdriver to push the remaining portions into the tank. After removing the lines, tip the trimmer and shake it to ensure that any small pieces of the fuel line fall out.

Clean the Tank: Before installing the new fuel lines, it is good practice to clean the fuel tank to remove any debris or residue that may have accumulated. Use a clean cloth or paper towel to wipe down the inside of the tank, ensuring no dirt or grime remains that could potentially clog the new fuel lines.

By following these steps, you will have successfully removed the old fuel lines from your weed eater trimmer, preparing it for the installation of the new fuel lines. Remember to refer to your diagram when installing the new lines to ensure a correct and proper fit.

Feed the new fuel lines into the tank

Now that you've removed the old fuel lines, it's time to feed the new ones into the tank. Cut the ends of the new fuel lines at an angle to make it easier to thread them into the tank. You can use needle-nose pliers to force the cut ends of the fuel lines into the proper holes in the tank. Push the larger vent line about an inch into the tank. As 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 you're having trouble getting the lines in, you can apply a small amount of oil to the outside of the line to help.

Once the lines are in place, you'll need to attach the fuel filter. Pull the smaller line out of the tank and cut the end of it square. Install the fuel filter onto this line, then drop it back into the tank. The fuel filter should be resting on the bottom of the tank.
