Replacing Fuel Line In A Johnsered Weed Wacker: A Guide

If you're a homeowner or a professional landscaper, you know the importance of keeping your tools in good condition. A weed wacker is a handy tool for maintaining your lawn and getting rid of weeds, but like any machine, it may require occasional maintenance and repairs. One common issue that owners experience is fuel line damage or wear. The fuel line is responsible for supplying fuel from the tank to the engine, and if it becomes cracked or clogged, it can hinder the trimmer's performance. Luckily, replacing the fuel lines on a weed wacker is a relatively straightforward process that can be done by yourself with the right tools and a little know-how.

How to Replace Fuel Lines on a Johnsered Weed Wacker

Disconnect the spark plug wire

Disconnecting the spark plug wire is an important step in replacing the fuel lines on your Johnsered weed wacker. Here is a detailed, step-by-step guide on how to do this:

Locate the Spark Plug Wire

The spark plug wire is usually located near the weed wacker's handle. Most models have a standard black wire and a tubular boot, but some may have a rectangular rubber boot that covers both the wire and the plug.

Remove the Boot

Use a flat-head screwdriver to gently pry upwards on the rubber boot while pulling it away from the plug with your other hand. This ensures that you don't damage the boot or the plug if it is stuck. Continue prying and pulling gently until the boot unsnaps and comes away from the plug.

Loosen the Spark Plug

Fit the appropriate-sized socket over the spark plug. The most common sizes are 5/8-inch, 3/4-inch, or 13/16-inch. Attach a 3/8-inch socket wrench to the socket. You may need a 3-inch wrench extension if the plug is difficult to reach.

Remove the Spark Plug

Turn the wrench sharply in a counterclockwise direction to loosen the plug. Once it is loose enough, you can finish unscrewing it with your fingers. Be sure to wear rubber gloves, as the plug will likely be greasy.

With the spark plug removed, you can now disconnect the spark plug wire. Simply pull the wire straight off the spark plug. It is important to do this in a well-ventilated area to avoid inhaling fumes.

Once the spark plug wire is disconnected, you can continue with the next steps of replacing the fuel lines. Remember to reconnect the spark plug wire and the spark plug once you have completed the fuel line replacement.

Remove the fuel filter

To remove the fuel filter from your Johnsered weed wacker, you'll need to first locate the fuel tank. Once you've found the tank, look inside for the fuel filter—it's a small, white cylinder attached to the end of the fuel line.

Next, you'll need to fish the filter out of the tank. You can use a pair of needle-nosed pliers or a straightened wire coat hanger with a hook on the end to do this. Simply hook the end of the hanger around the filter and pull it out. Alternatively, if you're using pliers, grip the filter firmly and carefully pull it out of the tank.

Once the filter is out, pull it off the end of the fuel line. Now you're ready to install the new fuel filter.

If you're having trouble finding the fuel filter, it might be helpful to consult the user manual for your specific Johnsered weed wacker model. This will ensure you're able to locate and remove the fuel filter correctly and efficiently.

Disconnect the lines from the carburetor

Disconnecting the fuel lines from the carburetor is a crucial step in maintaining your weed wacker and ensuring optimal performance. Here's a detailed, step-by-step guide on how to safely and effectively complete this task:

Firstly, before you begin, it is imperative to prioritise safety. Ensure your weed wacker's engine is cool and turned off. This will prevent any accidental ignition during the process.

Now, let's begin by locating the fuel lines. They are typically found near the rear of the vehicle, underneath the car. To relieve pressure in the fuel lines, remove the fuel pump fuse or the fuel pump relay. This will prevent any fuel from spraying out when you disconnect the lines.

The next step is to use a fuel line disconnect tool to remove the lines. This tool can be purchased at most automotive stores. Simply slide the tool over the fuel line and push it into the fitting. While holding the tool in place, carefully pull the line away from the fitting. Repeat this process for all the fuel lines that need to be disconnected.

Once the fuel lines are removed, thoroughly inspect them for any signs of damage or wear and tear. If you notice any issues, it is advisable to replace the fuel lines entirely.

Now, let's focus on the fuel lines connected to the carburetor. Using a pair of needle-nose pliers, carefully pull the fuel lines off the carburetor. If they are resistant, gently wiggle the pliers back and forth to loosen the connection before pulling.

Before removing the lines, it is a good idea to take a digital photograph or make a diagram of the fuel line configuration. This will serve as a reference when reconnecting the new fuel lines to the carburetor.

Additionally, pay attention to the routing of the fuel lines and take note of any fittings or filters attached. This information will be useful when installing the new fuel lines.

By following these detailed instructions, you can successfully disconnect the fuel lines from the carburetor of your Johnsered weed wacker, setting the stage for a smooth installation process. Remember to work carefully and refer to your owner's manual for any model-specific considerations.

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 Johnsered weed wacker. Here is a detailed, step-by-step guide on how to do this:

Firstly, locate the fuel tank on your weed wacker. The fuel tank is where the fuel lines originate, so you need to identify it before proceeding. Once you have found the fuel tank, you may need to remove the tank cover to access it fully. This will allow you to see the fuel lines clearly and prepare for their removal.

Now, let's move on to the fuel lines themselves. You will notice that there are two fuel lines connected to the tank. One line is for fuel input, which brings fuel from the tank to the engine, and the other is for fuel output, which returns any unused fuel back into the tank. Carefully observe the routing of these lines and take note of any fittings or filters attached to them. This will be important information for when you install the new fuel lines.

To safely remove the fuel lines, start by disconnecting the clamps or fittings that secure them to the tank. It is important to have a container or towel ready to catch any fuel that may spill during this process. Once the lines are disconnected, gently pull them out of the tank. If they are difficult to grasp, you can use needle-nose pliers to get a better grip. Be careful not to damage the lines or the surrounding components as you pull them out.

If you are unable to pull the lines out, you may need to cut them flush with the tank. Use a small screwdriver to push the remaining portions of the lines into the tank. After that, tip the weed wacker and shake it gently to ensure that any small pieces of the fuel lines fall out.

By following these steps, you will have successfully removed the old fuel lines from the tank. Now you can move on to the next step of installing the new fuel lines. Remember to work carefully and refer to the specific instructions for your Johnsered weed wacker model whenever possible.

Feed the new fuel lines into the tank

To feed the new fuel lines into the tank, you will need a new fuel line kit, scissors, and needle-nose pliers.

First, cut the ends of the new fuel lines at an angle to make them easier to thread into the tank. You can apply a small amount of oil to the outside of the line if needed. Next, use the 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, and push the smaller fuel supply line into the tank far enough so that the fuel filter will lay on the bottom of the tank.

Now, fish the smaller line out of the tank and cut the end square. Install the fuel filter onto the end of the smaller line and drop it back into the tank. Ensure that the fuel filter is weighted to always fall to the bottom. The vent line should just barely poke through the grommet, and the return line length is not specific or critical. The main line should be long enough to pull the filter out of the fill for service or replacement.
