The Poulan Chainsaw is a powerful tool for cutting and pruning, but it has had issues with its fuel lines, which are notoriously cheap and prone to breakage. The fuel lines are often made of a vinyl-like material and are fragile, requiring frequent replacement. The Poulan Chainsaw has two fuel lines, one connected to a fuel filter inside the tank, and the other, a return line, which goes to the primer. The primer bulb is used to pump fuel into the carburetor, and the second line is a vent hose that vents the gas tank so the fuel will flow. This design is a safety feature, allowing the saw to vent through a one-way valve near the carburetor rather than through the gas cap.

What You'll Learn
The Poulan 2150 chainsaw has a fuel line diagram that shows the routing of the fuel lines
The diagram outlines that there is one line to the primer bulb, and another line from the primer bulb to the carburettor. The primer bulb is used to pump fuel into the carburettor, which can then be mixed with air to power the chainsaw. The primer bulb has two nipples, marked "IN" and "OUT". The "IN" nipple is the negative, or pull pressure side, and the "OUT" nipple is the positive, or push pressure side. The fuel line from the primer bulb to the carburettor is the return line, which goes back to the tank.
The Poulan 2150 chainsaw has two fuel lines, which are both essential for the machine to function. One line goes from the fuel tank to the carburettor, and the other is the return line, which goes from the carburettor back to the tank. The fuel tank line is connected to a fuel filter inside the tank, and the return line usually has a fuel filter on the end.
The fuel lines on the Poulan 2150 chainsaw are known to be of poor quality and are prone to rotting and cracking, which can cause the chainsaw to malfunction.

The Poulan Chainsaw Fuel Line Kit is available for purchase
These kits are essential for Poulan chainsaw owners as the chainsaws are known for their fuel line issues. The fuel lines tend to be of low quality and are prone to cracking and rotting, often requiring replacement. The fuel lines on a Poulan chainsaw have two layers, with one line connected to a fuel filter inside the fuel tank, and the other, potentially a vent hose, connected to a one-way valve near the carburetor.
When purchasing a Poulan Chainsaw Fuel Line Kit, it is important to ensure you are getting the correct size line for your specific Poulan model. The kits come with varying fuel line sizes, such as 3/16" OD by 3/32" ID and 9/64" OD by 5/64" ID, and are compatible with different Poulan models.
By investing in a Poulan Chainsaw Fuel Line Kit, you can ensure your chainsaw remains in good working condition and avoid the frustration of a malfunctioning fuel line.

The fuel line is prone to breaking and rotting
The fuel line of a Poulan chainsaw is prone to breaking and rotting due to several factors. One of the main reasons is the use of cheap, low-quality materials that are not durable and can deteriorate over time. This results in frequent replacements, as the fuel lines become brittle, crack, and break into pieces.
The fuel line's softness and flexibility make it more susceptible to permeation, where fuel soaks into the hose and breaks it down, leading to cracks and leaks. This issue is exacerbated by the presence of ethanol in modern fuel, which can accelerate the deterioration of the hose material. Additionally, the fuel line may suffer from corrosion, especially in the metal parts, and age-related degradation, making it prone to breaking.
Abrasions caused by contact with other vehicle parts or debris can also weaken the fuel line and make it more prone to breaking. Furthermore, the design of the fuel line and its positioning within the chainsaw may contribute to its vulnerability. In some cases, the fuel line may be difficult to access for maintenance or replacement, requiring significant disassembly of other components.
To mitigate the issues with breaking and rotting fuel lines, it is recommended to use higher-quality materials, such as Tygon or Excelon, which are known for their resistance to fuel, diesel, and alcohol. Regular maintenance and inspections of the fuel line can also help identify signs of deterioration, such as cracks or leaks, and prompt replacement can prevent sudden failures.
When replacing a rotten fuel line, it is generally advisable to replace the entire line rather than just the affected section, as the rest of the line may also be close to failing. It is important to choose suitable replacement parts, such as steel, copper alloy, or reinforced rubber hoses, and ensure proper installation to prevent leaks and maintain the safety and performance of the chainsaw.

The fuel line is cheap and easy to replace
The fuel line in a Poulan chainsaw is cheap and easy to replace. This is fortunate, as fuel lines are in constant contact with gasoline, which means that over time, the gas will cause the fuel line to harden and deteriorate. This can lead to cracks and breaks in the line, which can be dangerous and cause air to enter the fuel system, causing the engine to run erratically, die, or not start.
There are multiple fuel lines found on most small engines, with a minimum of two lines: one carrying fuel from the tank to the carburetor, and a second line returning excess fuel from the carburetor to the fuel tank. Many models also have a third line between the remote purge bulb and the carburetor.
When replacing the fuel line, it is important to ensure that the correct size line is used, as it must fit very snugly through the hole in the tank. It is also important to be careful when reassembling the chainsaw, to avoid kinking the fuel line. The fuel tank may need to be removed to install the new fuel line, and the fuel filter may also need to be replaced at the same time.
There are detailed instructions available online for replacing the fuel line in specific models of Poulan chainsaws, such as the Poulan 2000, 3800, and P3314.

The fuel line is made from a cheap, almost vinyl material
The Poulan chainsaw's fuel line is constructed from a low-cost, vinyl-like material. This flexible, plastic-type substance is commonly used in fuel lines due to its ability to withstand the demands of the application. The vinyl material is durable yet pliable, making it ideal for fuel lines that need to be both sturdy and flexible. This allows the fuel line to bend and move without cracking or breaking, ensuring a reliable and consistent fuel supply to the engine.
While the specific type of vinyl used in the Poulan chainsaw's fuel line may vary, it is typically made from a blend of polyvinyl chloride (PVC) and other polymer compounds. This combination results in a material that is strong, chemically resistant, and capable of handling the fuel and oil mixture without degradation.
The choice of this vinyl material is likely driven by cost-effectiveness and durability. As a budget-friendly option, it helps keep the overall manufacturing expenses low, making the chainsaw more affordable for consumers. At the same time, the material's resilience ensures that the fuel line can withstand the rigors of chainsaw use, from vibration and movement to exposure to heat, moisture, and varying weather conditions.
This fuel line material is designed to be compatible with the fuel and oil mixture used in two-stroke engines, such as those commonly found in chainsaws. It can handle the potentially harmful and corrosive properties of the fuel mixture without breaking down or leaking, ensuring a safe and efficient operation.
While the vinyl material provides durability and cost benefits, it is important to note that it may not possess the same longevity as higher-end materials used in more expensive chainsaws. Over time, exposure to sunlight, extreme temperatures, and the fuel mixture itself can lead to brittleness or degradation of the fuel line, requiring replacement. Therefore, regular maintenance and timely fuel line replacements are crucial to ensure the optimal performance and longevity of the Poulan chainsaw.

Frequently asked questions
The Poulan Chainsaw may need a fuel line kit because the original fuel lines are made of cheap, low-quality material that can easily break or become brittle and rot.
One fuel line is connected to a fuel filter inside the fuel tank, while the other is a return line for the primer.
There is no set time for how often the fuel lines need to be replaced. However, it is recommended to check the fuel filter and lines for any damage or rotting when the tank is less than 1/3 full.
If your Poulan Chainsaw is revving up and dying after a few seconds, this could be a sign of a damaged fuel line. Other signs include the chainsaw running differently when the tank is full compared to when it is less than full.
Replacement fuel lines for Poulan Chainsaws can be purchased from authorised distributors or online retailers such as Amazon.
