Replacing Husqvarna 125B Blower Fuel Line: Step-By-Step Guide

The Husqvarna 125B leaf blower is a popular product, but some users have experienced issues with its fuel line. The fuel line may need to be replaced if the blower is leaking fuel, having trouble starting, or not drawing up any fuel when primed. This can be done by purchasing a fuel line repair kit, which typically includes a new fuel filter, fuel lines, and a primer bulb. However, some customers have reported issues with the quality of the fuel line in the repair kit, so it is important to carefully follow the instructions for proper installation.

How to identify the correct fuel line for your Husqvarna 125B blower

To identify the correct fuel line for your Husqvarna 125B blower, you can follow these steps:

Firstly, it is important to understand the components of the fuel system and their roles. The fuel line is responsible for delivering fuel from the tank to the carburettor, where it is mixed with air before entering the engine. The fuel filter ensures that contaminants are removed from the fuel, and the primer bulb helps to prime the engine by creating suction and drawing fuel into the system.

When identifying the correct fuel line, it is crucial to consider the dimensions and specifications of your blower. The fuel line should be compatible with the specific model of your Husqvarna 125B blower. You can refer to the owner's manual or search for the model number online to find the exact fuel line kit recommended by the manufacturer.

Additionally, examining the existing fuel line can provide valuable information. Check the length, diameter, and material of the current fuel line. Fuel lines can be made from different types of rubber or plastic, and ensuring compatibility with your blower is essential. The fuel line kit should include all the necessary components, such as the fuel filter and primer bulb, and ideally, a diagram or instructions for installation.

Online resources, such as forums and product reviews, can offer valuable insights. For example, in a forum post, a user shared their experience with a fuel line kit that included a diagram, making the installation process straightforward. They emphasised the importance of ensuring the fuel lines were not reversed and provided a detailed description of the correct fuel line routing.

Another user, in a product review, mentioned that the fuel line kit they purchased was a perfect fit for their Husqvarna 125B blower and that it came fully assembled, making the installation process easy. They also noted that the lines felt more durable and thicker than the original ones.

Therefore, when identifying the correct fuel line for your Husqvarna 125B blower, it is essential to consider the compatibility with your blower's model, examine the dimensions and material of the existing fuel line, and refer to online resources for additional guidance and insights from other users' experiences.

Step-by-step guide to replacing the fuel line

• Purchase a new fuel line repair kit. This should include a new fuel filter, fuel lines to the primer, and lines out to the engine.
• Disconnect the old fuel line from the fuel tank and carburetor. This may require removing the fuel tank and/or carburetor from the blower.
• Clean any residual fuel or debris from the fuel tank and carburetor.
• Connect the new fuel line to the fuel tank and carburetor, following the correct routing of the fuel lines. Refer to the blower's service manual or a diagram/description of how to run the new fuel lines. Ensure that the fuel lines are not reversed.
• Prime the motor and check for any leaks. If there are no leaks, reassemble the blower.
• Test the blower to ensure it is functioning properly.

Note: It is recommended to wear protective gear and work in a well-ventilated area when performing these steps.

Common issues when changing the fuel line and how to fix them

When changing the fuel line on a Husqvarna 125B blower, there are a few common issues that you may encounter. Here are some detailed instructions on how to fix them:

Fuel Line Installation

If you are installing a new fuel line, ensure that you have the correct size line for your model. The fuel line kit contains two different sizes, so you need to determine which one fits your blower. For the Husqvarna 125B, you will likely only need the large fuel line. Insert the tapered end of the new fuel line into the opening on the top of the fuel tank and feed approximately six inches of the line into the tank.

Fuel Line Routing

Another common issue is the routing of the fuel lines. The correct routing is critical for the proper functioning of the blower. The fuel line with the filter usually goes from the tank to the bottom connection on the carburettor, then from the top of the carburettor to the short hose barb on the primer bulb, and finally, from the long hose barb on the primer back to the tank. This allows the primer to pull fuel from the tank, through the carburettor, and return it to the tank.

Clogged or Cracked Fuel Lines

Over time, fuel lines can become clogged, crimped, or cracked, restricting gas flow and preventing the engine from starting or running properly. Clear any clogs and check for any cracks or damage in the fuel lines. If there are any issues, replace the fuel lines with manufacturer-approved parts.

Fuel Line Reversal

If the fuel lines are connected incorrectly, the primer bulb may not fill with gas. Ensure that the lines are routed correctly, paying attention to the short and long lines, and that the grommet is properly positioned.

Carburettor Issues

If the fuel lines are correct and the primer still does not work, the problem may lie with the carburettor. Check for leaks in the carburettor, and if necessary, rebuild or replace it.

Fuel Tank Issues

Ensure that the fuel tank is not empty and that the fuel lines are connected correctly to the tank. Check for any blockages or restrictions in the fuel lines that may prevent fuel from reaching the primer bulb.

When encountering issues with changing the fuel line on a Husqvarna 125B blower, carefully inspect the fuel lines, their routing, and connections. Ensure that the carburettor and fuel tank are also functioning properly. By following the above instructions, you should be able to identify and resolve common issues with the fuel line replacement process.

Where to buy a replacement fuel line

If you're looking to buy a replacement fuel line for your Husqvarna 125B blower, there are a few options available to you. You can either purchase a fuel line repair kit directly from Husqvarna or try online retailers such as Amazon.

How to prevent future fuel line problems

To prevent future fuel line problems, it is important to ensure that the fuel lines are connected correctly. The fuel line with the filter should be attached to the bottom connection of the carburettor, with the other line attached to the top. The primer bulb should have a return hose to the tank and a connection to the carburettor. It is also important to check that the fuel lines are not reversed, as this can cause issues with the fuel flow.

Regular maintenance and inspection of the carburettor are crucial to preventing fuel line problems. This includes cleaning or replacing the carburettor, as well as checking the spark plug, air filter and fuel filter. It is also recommended to drain the fuel before storing the blower to prevent clogged carburettors and issues with stale fuel.

Additionally, the primer bulb should be inspected regularly to ensure proper fuel flow to the carburettor. The bulb should be assembled correctly, with distinct suction and pressure sides. The return line from the primer bulb should be linked properly back to the tank to prevent fuel starvation or flooding.

Finally, it is important to use the correct fuel-to-oil mixture ratio as specified by the manufacturer to ensure optimal engine health and performance.
