Replacing the fuel line in a Craftsman Weedwacker is a relatively straightforward task. The fuel line can be accessed by removing the fuel tank and feeding the new line through the hole in the bottom of the tank. It is important to ensure that the correct type of fuel line is used, as some lines may not be compatible with the alcohol in modern gas. The fuel filter should also be checked and replaced if necessary. When reassembling the fuel lines, it is important to cut the first 1/4 inch of the line at a bias and apply a small amount of dish detergent before pushing it through the corresponding tank hole. Additionally, it is recommended to replace the primer bulb and ensure that the fuel lines are snugly fitted to prevent leaks.
What You'll Learn
Removing the old fuel line
To remove the old fuel line from your Craftsman Weedwacker, you will need to first detach the fuel tank. Once the fuel tank is removed, clean it thoroughly.
Next, you will need to remove the old fuel line from the tank. This can be done by cutting the first 1/4 inch of the fuel line at an angle and using a pair of needle-nose pliers or forceps-style pliers to pull the line through the corresponding hole in the tank. If the fuel line is difficult to grasp with the pliers, you can try sanding down the end of the line to create a smoother surface.
Alternatively, you can use a coat hanger to pry the fuel line out of the tank. This method may be easier if the fuel line is stubborn or difficult to grasp with pliers.
Once the fuel line is removed from the tank, you can dispose of it or keep it for reference when installing the new fuel line. It is recommended to purchase a new fuel filter and primer bulb when replacing the fuel line to ensure optimal performance.

Sourcing a new fuel line
When sourcing a new fuel line for your Craftsman Weedwacker, there are a few things to keep in mind. Firstly, identify the size of the fuel line you need. The fuel line sizes commonly used in Craftsman Weedwackers are 0.080 x 0.140 inches and 3/32" x 3/16". You can purchase fuel lines in these sizes from various retailers, including Sears, Amazon, and eBay.
When purchasing a new fuel line, consider buying a fuel line kit, which will include additional parts such as a primer bulb, fuel filter, and grommets. These kits are available on Amazon and eBay, as well as from specialist small engine repair shops and weed trimmer dealers.
If you are unable to find a fuel line kit that matches your specific Craftsman Weedwacker model, you can also purchase individual parts separately. For example, you can buy fuel lines, primer bulbs, and fuel filters separately on Amazon, eBay, and from retailers such as AutoZone.
It is important to note that fuel lines are typically made of rubber or plastic, and these materials can deteriorate over time due to exposure to gasoline and ethanol. When replacing your fuel line, consider upgrading to a fuel line that is designed to withstand exposure to ethanol, as this will help prevent future deterioration and fuel system issues.
Finally, when purchasing a new fuel line, be sure to consult your Craftsman Weedwacker's owner's manual for specific instructions and parts information. This will help ensure that you source the correct parts and have a smooth installation process.

Running the new fuel line into the tank
Once you have the correct size, cut the first 1/4 inch of the new fuel line at a steep angle, and apply a small amount of dish detergent to the end. This will make it easier to push the line through the hole in the bottom of the tank. Use a pair of needle-nose pliers to feed the line through the hole, and stop when it is far enough into the tank.
Now, attach the fuel filter to the end of the fuel line inside the tank. Ensure that the filter is long enough to reach the bottom of the tank in any position, so that it can always draw fuel. You can also attach the fuel filter to the fuel line outside the tank, using the black plastic connector that comes with some kits.
Finally, reattach the fuel tank securely, and ensure that all connections are tight to prevent leaks.

Attaching the new fuel line to the fuel filter
To attach the new fuel line to the fuel filter of your Craftsman Weedwacker, follow these steps:
Firstly, ensure you have the correct size of fuel line for your model. You can do this by checking the owner's manual or by measuring the diameter of the old fuel line. Fuel lines can be purchased at hardware stores, auto shops, or online. It is recommended to buy a fuel line that is rated for alcohol if your fuel contains ethanol.
Next, cut the new fuel line at a steep angle to make it easier to push through the hole in the fuel tank. Apply a small amount of dish detergent to the end of the line to act as a lubricant. Use a pair of needle-nose pliers or forceps-style pliers to guide the line through the hole and pull it up until you have enough slack to reach the fuel filter.
Now, you can attach the fuel filter to the fuel line. The fuel filter should be placed inside the fuel tank and positioned so that it sits at the bottom of the tank in any position. This can be done by attaching the fuel filter to the end of the fuel line and then threading the line back through the hole in the tank. Ensure that the fuel filter is secure and won't detach from the line.
Finally, adjust the length of the fuel line inside the tank so that it reaches the bottom and cut off any excess. Make sure that the fuel line is not too tight or restricted in any way.
By following these steps, you should be able to successfully attach the new fuel line to the fuel filter on your Craftsman Weedwacker.
