how to rewire fuel lines for poulan chainsaw

Rewiring the fuel lines of a Poulan chainsaw is a straightforward task that can be completed in under an hour. It is important to get the right-sized replacement fuel lines to avoid leaks or performance issues. The first step is to locate the fuel tank, which is usually situated near the rear handle. Once the fuel tank is located, it should be emptied to avoid spills or leaks. The next step is to identify the old fuel lines connected to the tank and carefully detach them using tools such as needle-nose pliers or hemostats.

Prepare your workspace and tools

To prepare your workspace and tools for rewiring the fuel lines of your Poulan chainsaw, follow these steps:

Firstly, ensure you have a well-lit and ventilated workspace with ample room to work on your chainsaw comfortably. A well-lit workspace will ensure you can clearly see the intricate components of the chainsaw and reduce the risk of any accidents. Additionally, good ventilation will help dissipate any fuel vapours, enhancing safety during the rewiring process.

Next, gather all the necessary tools and materials before beginning the fuel line replacement. This preparation will make the task smoother and more efficient. The required tools may vary depending on your specific Poulan chainsaw model, but here is a general list:

  • New fuel lines that are the correct size and length for your chainsaw model.
  • Safety gloves to protect your hands from injury and debris.
  • Safety glasses to shield your eyes from potential debris or fuel splashes.
  • A screwdriver set, including both flat-head and Phillips-head screwdrivers, for the different screws on the chainsaw.
  • Needle-nose pliers for detaching and guiding fuel lines.
  • Hemostats for removing the compression fitting and any stubborn fuel line pieces.
  • A utility knife for cutting and separating fuel lines from fittings.
  • Wire cutters or scissors for cutting fuel lines.
  • A ratchet/socket set for manipulating various chainsaw components.
  • Long-nosed pliers for reaching and gripping in tight spaces.
  • A receptacle for draining fuel.

Having the right tools and materials will make the rewiring process safer, faster, and more efficient. It is also important to note that you should always wear the necessary safety gear, including gloves and safety glasses, when working on your chainsaw to protect yourself from injury.

Drain the fuel tank

To begin rewiring the fuel lines of your Poulan chainsaw, the first step is to drain the fuel tank. This is a crucial safety precaution to avoid spills or leaks during the rewiring process. Here's a detailed guide on how to drain the fuel tank:

Prepare Your Work Area

Ensure you have a well-lit and well-ventilated workspace with ample room to work on your chainsaw comfortably. It is important to have good visibility and a clutter-free space to work efficiently and safely.

Locate the Fuel Tank

The fuel tank on your Poulan chainsaw is typically situated near the rear handle. Once you have located the fuel tank, the next step is to empty it completely.

Remove the Spark Plug Wire and Air Filter

Before draining the fuel tank, it is important to disconnect the spark plug wire and remove the air filter, along with its housing. This will ensure that the chainsaw is inactive during the process, preventing any accidental startups.

Now, you can proceed to drain the fuel from the tank. Place a receptacle or container underneath the fuel tank to catch the drained fuel. Slowly and carefully pour out the fuel from the tank into the receptacle. Be cautious to avoid any spills or leaks during this step. Ensure that you are wearing appropriate safety gear, such as safety gloves and safety glasses, to protect yourself from any fuel splashes.

Clean the Fuel Tank

After draining the fuel tank, it is good practice to clean it thoroughly. Use a clean cloth or paper towel to wipe down the interior and exterior of the fuel tank, ensuring that any residual fuel or debris is removed. This step will help maintain the chainsaw's performance and prevent the buildup of dirt or grime.

By following these steps, you will have successfully drained and prepared your Poulan chainsaw's fuel tank for the rewiring process. Remember to always prioritize safety and have the necessary tools and knowledge before proceeding with any maintenance or repair work on your chainsaw.

Detach the fuel lines

Detaching the fuel lines from your Poulan chainsaw is a crucial step in maintaining the efficiency and safety of your equipment. Here is a detailed guide on how to detach the fuel lines:

Prepare Your Workspace and Gather Tools

Firstly, ensure you have a well-lit and ventilated workspace with ample room to work on your chainsaw comfortably. It is important to have the necessary tools and materials ready before starting the fuel line detachment process. The tools you will need include needle-nose pliers, safety gloves, safety glasses, and a screwdriver set.

Locate and Empty the Fuel Tank

Locate the fuel tank on your chainsaw, typically situated near the rear handle. Completely empty the fuel tank to avoid spills or leaks during the detachment process.

Identify and Detach the Fuel Lines

Identify the old fuel lines connected to the tank. There are usually two lines: one for fuel intake and another for the return. Carefully detach these fuel lines using needle-nose pliers. Note that in some cases, you may need to remove screws before detaching the fuel line from the primer bulb. This can also be done using pliers.

Inspect and Clean

Before removing the fuel lines entirely, take note of their routing in the chainsaw. This will be helpful when installing new lines. Inspect the old fuel lines for any signs of wear, cracks, or damage, and if any issues are found, replace them promptly. Finally, clean the area around the fuel tank and fuel lines to remove any dirt or debris that could interfere with the reattachment of new fuel lines.

Detaching the fuel lines from your Poulan chainsaw is an important step in maintaining and ensuring the smooth operation of your equipment. By following these steps, you can safely and effectively remove the old fuel lines, setting the stage for the installation of new ones.

Clean the area and inspect the old fuel lines

To rewire the fuel lines for your Poulan chainsaw, you must first clean the area and inspect the old fuel lines. Here is a step-by-step guide:

Clean the Area

  • Ensure your Poulan chainsaw is turned off and cool to the touch before starting any work.
  • Put on safety gloves and glasses to protect your hands and eyes during the maintenance process.
  • Locate the fuel lines by examining the placement near the fuel tank. The main fuel line connects to the bottom of the fuel tank, while the return line attaches to the top.
  • Drain the fuel tank and remove the fuel cap.
  • Using a clean cloth or compressed air, clean the inside of the fuel tank to remove any debris or residue.
  • Clean the area around the fuel tank and fuel lines to eliminate any dirt or debris that could interfere with the replacement process.

Inspect the Old Fuel Lines

  • Note how the old fuel lines are routed in the chainsaw. This will help you when installing the new lines.
  • Inspect the old fuel lines for any signs of wear, cracks, leaks, or damage.
  • If you notice any issues, it is crucial to replace them promptly.
  • Dispose of the old fuel lines safely and prepare for the installation of the new ones.

Feed the new fuel lines

To feed the new fuel lines, start by feeding them into the fuel tank through the holes where the old lines were removed. Needle-nose pliers can help guide the lines through. You can also use hemostats or a tool that comes with a small engine fuel line kit, which is basically a thin piece of wire attached to a key ring. Thread the wire through the hole in the tank, attach the line cut to a sharp point to the wire by poking it through, then close the end of the wire tightly with some pliers. If you close it tight, the wire and fuel line should have just enough clearance to pull through.

The new fuel lines should be cut to the length of the original fuel lines. Cut an angle on one end of the new fuel line to make it easier to insert into the fuel tank. Lubricate the lines with a drop of oil to make the process easier.

Push the fuel filter line into the tank enough so it can be pulled out from the other side through the tank opening. Take it out from the opening but not too much. Make a square cut on that end and install the fuel filter. Now, pull the line back up from the other side using pliers until the filter resets at the bottom of the tank.
