The fuel line size of a Poulan chainsaw depends on the model. For example, the Poulan 4000 requires a 1/8 X 3/16 fuel line, while the Poulan 2150 has a more complex fuel line routing system with lines connecting the primer bulb and the carburetor. The fuel line length of the Poulan 4000 is 9.5, with 5 going to the carb and 4 inside the tank. The Poulan 2400 Woodmaster is another model that has been mentioned to have fuel line issues. There are fuel line kits available for purchase that are compatible with various Poulan chainsaw models.

The Poulan 2150 chainsaw fuel line routing
The Poulan 2150 chainsaw's fuel line routing is a common issue for owners of this model. The fuel line from the tank to the carburettor is the smaller diameter line. This line can be replaced with a 3/32" inner diameter and 3/16" outer diameter Tygon fuel line. This can be achieved by enlarging the hole in the top of the fuel tank with an appropriate drill bit.
Some owners have opted for a 3/16" OD fuel line instead of the small fuel line, which requires an 11/64" diameter hole. This is a good fix for smaller Poulan saws.
The fuel line routing diagram for the Poulan 2150 shows one line to the primer bulb, and the other from the primer bulb with two inlets on the carburettor. The barbed fitting is for fuel, and the smooth brass fitting is the return to the tank.
Some owners have reported issues with their Poulan 2150 chainsaws, including the machine idling and then dying when the trigger is pulled. Others have reported that the machine will run while cold but not while hot, quitting after a few minutes.

The Poulan 4000 fuel line size
The Poulan 4000 is a chainsaw with a fuel line size of 1/8 X 3/16 inches. This is a common fuel line size, but it is essential to get the right fit for the barb for the duckbill check valve on the vent line.
When replacing the fuel lines on the Poulan 4000, it is important to note that there are two lines: one connected to a fuel filter inside the fuel tank, and the other is a vent. The first line runs from the fuel tank to the carburetor, while the second line is the return line for the primer, sticking down into the tank about half an inch. It is recommended to have about 2 feet of line to work with when replacing the fuel lines.
The process of replacing the fuel lines involves removing the air filter cover, air filter, and cylinder cover. This requires removing a few screws of different lengths, which should be noted for reassembly. The fuel tank will then be exposed, and the fuel lines can be accessed. It is important to ensure that the correct size line is used, as mentioned earlier, to achieve a very snug fit through the hole in the tank.
Some users have mentioned using thin-gauge stove pipe wire and medium-sized curved hemostats to aid in the process. It is also recommended to cut the line at an angle, allowing for easier insertion and removal using pliers. Additionally, it is worth noting that the Poulan 4000 can use the Oregon brand fuel lines, which are designed to withstand 30% ethanol.

Chainsaw fuel line routing diagrams
Chainsaw fuel lines are a common source of frustration for many users, with some people opting to replace their chainsaw entirely rather than deal with the fuss of replacing them. However, with the right knowledge, you can successfully replace your fuel lines and get your chainsaw working again.
The first step is to determine the size of the fuel line that you need. For a Poulan 4000, for example, you will need a 1/8 X 3/16 line. This is a very common line size and is especially needed for a proper fit with the barb for the duckbill check valve on the vent line. The total fuel line length should be 9.5", with 5" going to the carburetor and 4" inside the tank.
Once you have the correct size, you need to cut the line at an angle. This will allow you to stick the point through, grab it with pliers, and pull it through. The fuel line that comes out of the fuel tank connects to the nipple on the carburetor with a 90-degree bend. The inlet on the end plate gets connected to your impulse line, which then connects to the bottom of the cylinder. This is a vacuum line that helps pump the fuel through your carburetor.
For a Craftsman chainsaw (358.352180), the process is similar. This saw has a primer bulb with two nipples, one marked "TANK" and the other "CARB". The large diameter line (3/16" OD) is routed from the primer bulb to the large hole in the top of the tank. The small diameter line (9/64" OD) goes to the carburetor. It is important to ensure that the routing is correct, as some diagrams may be misleading.

Fuel line maintenance and repair
Maintaining and repairing the fuel line of your Poulan chainsaw is a relatively straightforward process. It is important to perform regular maintenance checks on your chainsaw to ensure that the fuel line is in good condition and free of any debris or blockages. Here is a step-by-step guide to help you with fuel line maintenance and repair for your Poulan chainsaw:
Fuel Line Maintenance:
- Regular Inspection: It is recommended to inspect the fuel line regularly for any signs of wear, cracks, leaks, or debris build-up. Ensure that the fuel line is intact and securely connected to the tank, carburettor, and other components.
- Clean the Fuel Line: If you notice any dirt or debris on the fuel line, clean it using a soft cloth or brush. Make sure to remove any residue or deposits that may accumulate over time.
- Check for Clogs: Inspect the fuel line for any clogs or blockages, especially at the connections and bends. A clogged fuel line can restrict fuel flow and affect the performance of your chainsaw.
- Fuel Filter Maintenance: The fuel filter plays a crucial role in preventing debris and contaminants from entering the engine. Regularly inspect and replace the fuel filter as recommended by the manufacturer. A clogged fuel filter can cause starting problems and reduced engine performance.
Fuel Line Repair:
- Replacing the Fuel Line: If the fuel line is damaged or severely clogged, you may need to replace it. Refer to your Poulan chainsaw's manual for specific instructions and part numbers. Make sure to purchase a compatible fuel line with the correct dimensions and specifications.
- Tools and Preparations: Gather the necessary tools for the repair, such as a Phillips screwdriver, Torx drivers, hemostats, a utility knife, a ratchet/socket set, wire cutters or scissors, and long-nosed pliers. You will also need a receptacle to drain the fuel from the tank before beginning the repair.
- Removing the Old Fuel Line: Drain the fuel from the tank and disconnect the fuel line from the carburettor and tank. Carefully pull out the old fuel line, taking note of its routing and any clips or fasteners that secure it in place.
- Installing the New Fuel Line: Cut the new fuel line to the appropriate length, making sure it matches the old line. Install the new fuel line by reversing the removal process. Secure the fuel line in place and ensure all connections are tight and secure.
- Refilling and Testing: Once the new fuel line is installed, refill the fuel tank and check for any leaks. Start the chainsaw and let it run for a few minutes to ensure proper fuel flow and engine performance.
It is important to follow safety precautions when working with fuel and power tools. Always work in a well-ventilated area and wear appropriate protective gear, including gloves and eye protection. Refer to your Poulan chainsaw's manual or seek assistance from a qualified technician if you have any questions or concerns during the maintenance or repair process.
