Replacing Fuel Lines: Poulan 1950 Step-By-Step Guide

If you're looking to replace the fuel lines on your Poulan 1950, it's likely that you've been experiencing some frustrating sputtering and stalling issues. This is a common problem that can often be solved by changing the fuel lines, restoring your chainsaw to its full power and efficiency.

Before you begin, ensure you have the correct-sized fuel lines for your Poulan 1950 model, as well as safety gloves, safety glasses, a screwdriver set, needle-nose pliers, and scissors or wire cutters. You'll also want to work in a well-lit and ventilated area.

First, empty the fuel tank to avoid spills and carefully detach the old fuel lines using needle-nose pliers, noting how they are routed. Check the lines for any damage and clean the area. Next, feed the new lines into the tank, attach the fuel filter, and connect the other ends to the carburetor, trimming any excess. Finally, double-check that the lines are secure and test your chainsaw, inspecting for leaks and observing its performance.

Identify the old fuel lines

To identify the old fuel lines on your Poulan 1950 chainsaw, you must first locate the fuel tank, which is usually situated near the rear handle. Once you've found the tank, empty it completely to avoid any spills or leaks during the maintenance process.

Now, let's identify the fuel lines. There are typically two lines connected to the fuel tank: one for fuel intake and another for the return of excess fuel. Use needle-nose pliers to carefully detach these lines from the tank, being gentle to prevent any damage to the chainsaw's components.

After detaching the lines, take note of their routing within the chainsaw. Observe how they are connected to the tank, the carburetor, and any other relevant components. This information will be crucial when you install the new fuel lines.

Before removing the old fuel lines, it's a good idea to inspect them for any signs of wear, cracks, or damage. If you notice any issues, it's important to replace them as soon as possible to maintain the proper functioning of your chainsaw and to prevent safety hazards.

Finally, clean the area around the fuel tank and fuel lines to remove any dirt or debris that could hinder the installation of the new fuel lines.

Remove the old fuel lines

To remove the old fuel lines from your Poulan 1950, you must first prepare your workspace. Ensure you have a well-lit and clear area to work in. Next, locate the fuel tank, usually near the rear handle, and empty it completely to avoid spills.

Now, identify the old fuel lines. There are typically two: one for fuel intake and another for the return. Carefully detach these lines using needle-nose pliers, being gentle to avoid damaging other components. Take note of the routing of the old fuel lines, as this will be important when installing the new ones.

Inspect the old fuel lines for any signs of wear, cracks, or damage. If issues are present, it is vital to replace them promptly for the optimal performance and safety of your chainsaw. Finally, clean the area around the fuel tank and fuel lines to ensure no dirt or debris will cause issues during the replacement process.

Clean the area around the fuel tank

To clean the area around the fuel tank of your Poulan 1950, follow these steps:

Drain the fuel tank

Before beginning any work on your chainsaw, it is important to ensure that the fuel tank is drained. This will prevent any fuel from leaking and reduce the risk of fire.

Remove the top cover

Locate and remove the screws securing the top cover to the chainsaw. Once the screws are removed, lift the cover away from the saw.

Remove the air filter housing

Take off the air filter cover and remove the air filter from the housing. Next, remove the screw that secures the air filter housing to the engine, followed by the nuts that hold it in place. Lift the housing away from the carburetor assembly.

Disconnect components from the carburetor

Pull and hold the throttle trigger to expose the throttle linkage attachment point. Disconnect the linkage from the throttle trigger and then from the carburetor. Carefully slide the carburetor assembly off the mounting bolts and away from the engine. Use long-nosed pliers to disconnect the fuel intake line from the carburetor.

Clean the area

With the fuel tank exposed, you can now clean the area around it. Use a soft, clean cloth to wipe down the area, ensuring that any dirt, debris, or grease is removed. Pay close attention to the area where the fuel lines connect to the tank, as this is where residue often builds up. You may need to use a small brush or cotton swab to reach tight spaces.

Reinstall components

Once the area is thoroughly cleaned, carefully reinstall the carburetor, air filter housing, and top cover, following the previous steps in reverse. Ensure that all components are securely fastened before proceeding.

Refill the fuel tank

Now that the area around the fuel tank has been cleaned, you can refill the tank with fresh fuel. Be sure to use the appropriate fuel-oil mixture for your chainsaw, as specified in the owner's manual.

Feed the new fuel lines into the fuel tank

To feed the new fuel lines into the fuel tank of your Poulan 1950, follow these steps:

Firstly, feed the new fuel lines into the fuel tank through the holes where the old lines were removed. You can use needle-nose pliers to guide the lines through and ensure they are inserted smoothly.

Next, attach the fuel filter to the end of the fuel line inside the tank. This is an important step as it prevents debris from entering the carburetor and ensures a smooth, uninterrupted flow of fuel.

Now, connect the other ends of the new fuel lines to the carburetor. Ensure a secure fit to prevent any leaks that could affect the chainsaw's performance. A snug fit is essential to prevent fuel leaks when operating the chainsaw.

Finally, trim any excess length of the fuel lines, leaving just enough to comfortably connect to the tank and carburetor without kinking or bending. This ensures the fuel lines are neat and tidy, reducing the risk of accidental snags or tangles.

Some additional tips from a Poulan expert include cutting the end of the line at a 30-degree angle to create a sharp point and using a piece of trimmer line to guide the fuel line through the hole in the bottom of the tank.

Attach the fuel filter to the new fuel lines

To attach the fuel filter to the new fuel lines, follow these steps:

Firstly, ensure the fuel filter is securely attached to the end of the fuel line inside the tank. This is a crucial step to prevent debris from entering the carburettor and ensure a smooth flow of fuel. Make sure the fuel filter is positioned so it can fall to the low point in the tank, depending on how you hold the chainsaw.

Next, connect the other end of the fuel line to the carburettor. Ensure a tight, secure fit to prevent any fuel leaks that could affect the chainsaw's performance.

Finally, trim any excess length of the fuel line, leaving just enough to comfortably connect to the tank and carburettor without kinking or bending. Double-check that the new fuel lines are securely attached to both the tank and the carburettor. A snug fit is essential to prevent fuel leaks during operation.

Testing your Poulan 1950 after replacing the fuel lines is vital to ensure optimal performance and safety. Fill the tank with fuel and monitor for any leaks around the fuel line connections. Prime the engine according to your chainsaw's manual to ensure proper fuel flow, then attempt to start the chainsaw. Observe its performance, looking for smooth idling, consistent power, and proper acceleration.
