Replacing The Fuel Line In Your Stihl Wood Boss Chainsaw

The Stihl 028 Wood Boss is a chainsaw that may eventually experience sluggish performance due to a clogged fuel filter or a deteriorated fuel line. The fuel line is made of rubber, PVC, or viton and supplies fuel from the tank to the carburetor. Over time, the fuel line may crack, break, or develop pinholes, necessitating a replacement. This can be done by pulling the carb off and disconnecting the throttle.

The fuel line's purpose is to supply fuel from the tank to the carburetor

The fuel line in a Stihl 028 Wood Boss chainsaw is a crucial component responsible for delivering fuel from the tank to the carburetor. Over time, the fuel line can deteriorate due to exposure to ethanol, dry rot, and gasoline. When this happens, it's essential to replace the fuel line to ensure the proper functioning of the chainsaw.

The fuel line is designed to supply fuel from the tank to the carburetor, ensuring a consistent and efficient flow of fuel. This process is essential for the chainsaw's performance and longevity. A clogged or damaged fuel line can result in a lean fuel mixture, leading to internal engine failure. Therefore, it is important to inspect and replace the fuel line regularly.

The Stihl 028 Wood Boss fuel line is typically made of rubber, PVC-formulated compounds, or viton material. These materials are flexible and can be cut to the required length. However, rubber fuel lines tend to perish over time and can rub through if not properly secured. On the other hand, PVC and viton fuel lines offer improved durability and resistance to deterioration.

When replacing the fuel line, it is important to ensure that the line is securely connected to the fuel tank and the carburetor. A loose connection can result in air leaks, causing poor performance or a lean fuel mixture. Additionally, the fuel filter, located in the fuel tank, plays a crucial role in filtering the fuel before it reaches the carburetor.

By understanding the purpose and function of the fuel line in the Stihl 028 Wood Boss chainsaw, you can ensure proper maintenance and optimal performance of your equipment. Regular inspection and replacement of the fuel line and fuel filter are essential to keep your chainsaw running smoothly and efficiently.

The fuel filter is connected to the fuel line with a barb fitting

The fuel filter on your Stihl 028 Wood Boss is connected to the fuel line with a barb fitting. This is a very common type of fitting, used in a wide range of applications, from beverage filters to aquarium pumps.

A barb fitting is a unique-looking piece of plastic, steel, or brass. It has a barb that holds onto the tubing. In this case, the tubing is the fuel line. The barb fitting is inserted into the fuel line and the barb grips the interior wall of the tubing, creating a seal without damaging the tubing wall.

To install the fitting, you push the fuel line onto the barb. The barb fitting will hold onto the fuel line by itself, but you can also add a hose clamp for extra stability.

When it comes time to disconnect the fitting, you'll need to cut the tubing with a knife, as the barb design won't allow you to simply pull the tubing off.

The fuel filter on your Stihl 028 Wood Boss is located in the fuel tank and is weighted to keep it at the bottom of the tank. This ensures proper filtering and flow, regardless of the angle of the saw.

The fuel filter is located in the fuel tank and is weighted to stay at the bottom

The Stihl 028 Wood Boss fuel filter is located at the bottom of the fuel tank. It is weighted to ensure that it stays at the bottom of the tank, allowing for proper filtering and flow at any angle.

To replace the fuel filter, you can put the filter in the tank first and then insert the fuel line from the bottom. You can use a small pair of needle-nose pliers to pull the line through. Alternatively, you can wrap a small piece of wire around the top of the fuel line and use it to pull the line up into the hole.

The fuel filter should be replaced regularly or when a tune-up is performed to ensure optimal performance. A dirty fuel filter can significantly hinder the performance of the saw.

The fuel line is made of rubber, PVC, or viton

The Stihl 028 Wood Boss fuel line is made of rubber, PVC, or viton. These materials are chosen for their ability to transport fuel from the tank to the carburetor effectively and safely.

Rubber fuel lines are commonly used in the automotive and mechanical industries, offering several advantages over other materials. They are flexible, making them easy to fit into different systems. Rubber, especially nitrile rubber, also has high chemical resistance, which is crucial when working with fuels and oils. Additionally, rubber fuel hoses can withstand higher pressures than plastics due to their flexibility. However, rubber fuel lines may degrade faster and need more frequent replacement. They are also more susceptible to abrasions, especially when in contact with metals, so proper securing is essential.

PVC, or polyvinyl chloride, is a widely produced synthetic polymer known for its flexibility. PVC fuel hoses are lightweight, making them suitable for smaller machinery where weight is a concern. They are also low-cost, chemically resistant, and durable. On the downside, PVC piping is stiffer, limiting its flexibility in certain applications. It is not suitable for high-pressure or high-temperature uses, as it may burst or warp, leading to safety issues.

Viton is another option for fuel lines, known for its durability and ability to withstand high temperatures. While it may not be as flexible as some other materials, it provides long-lasting performance.

When choosing a fuel line material, it is essential to consider factors such as chemical resistance, pressure resistance, temperature resistance, and longevity. The type of fuel used and the specific application will also influence the decision between rubber, PVC, or viton fuel lines.

The fuel line should be replaced when it is cracked, broken, or has developed pinholes

The fuel line on a Stihl 028 Wood Boss chainsaw will need to be replaced if it is cracked, broken, or has developed pinholes. The fuel line's purpose is to supply fuel from the tank to the carburetor. Over time, the Stihl 028 Wood Boss fuel line will deteriorate due to exposure to ethanol, dry rot, and gasoline.

A broken fuel line can cause serious issues, including fuel leaks, poor fuel economy, and even a vehicle fire. Fuel can soak into the hose and break it down over time, causing cracks and leaks. This is known as permeation and is a common issue with soft, flexible hoses.

When replacing the fuel line, it is important to note that the Stihl 028 Wood Boss uses a fuel line made of either rubber, PVC-formulated compounds, or viton material. The replacement process will depend on the type of fuel line and the location of the break.

For example, if the break is near the fuel filter, it is recommended to purchase a new fuel line with a flare and threaded connector already installed, making the replacement easier. If the break is elsewhere, you will need to cut and replace that section of the line, ensuring a perfect cut to guarantee a leak-free connection.

It is also crucial to take safety precautions when working on a fuel line. Keep all sources of ignition away from the area to prevent accidental fires. Do not use electric tools as even one drop of fuel or vapor coming into contact with an electric arc can be extremely dangerous.
