Replacing Poulan Pro Pp5020av Fuel Lines: A Step-By-Step Guide

The Poulan Pro PP5020AV is a chainsaw that may require fuel line replacements. The fuel line is a clear, plastic line that delivers fuel and is 25 inches long. Replacements can be purchased online and installed with a screwdriver, pliers, socket set, and nut driver.

Fuel filter cleaning

To clean the fuel filter on a Poulan Pro PP5020AV chainsaw, you will need to purchase a replacement kit that includes a new fuel filter. This is because the fuel filter on this model is not designed to be cleaned and reused.

• Purchase a suitable replacement kit. Ensure that it is compatible with the Poulan Pro PP5020AV model.
• Prepare the chainsaw by placing it on a flat surface and disconnecting the spark plug to prevent accidental starting.
• Locate the fuel lines and the fuel filter. The fuel filter is usually found along the fuel lines, which run from the fuel tank to the carburettor.
• Using a pair of pliers or a line wrench, carefully detach the fuel lines from the fuel tank, carburettor, and fuel filter. Take note of the routing and orientation of the fuel lines for reassembly.
• Dispose of the old fuel filter and fuel lines responsibly.
• Install the new fuel filter and fuel lines. Cut the new fuel lines to match the length of the old lines, if necessary. Securely attach the new lines to the fuel tank, carburettor, and new fuel filter, following the original routing.
• Check for any leaks by filling the fuel tank and observing the connections for any signs of fuel dripping or spraying.
• Reconnect the spark plug and start the chainsaw to ensure proper operation.

By following these steps, you will have successfully replaced the fuel filter and cleaned the fuel lines on your Poulan Pro PP5020AV chainsaw.

Fuel line replacement

Step 1: Purchase a suitable replacement fuel line kit

Before you begin, you will need to purchase a replacement fuel line kit for the Poulan Pro PP5020AV. You can find these online or at your local hardware store. Make sure to buy a kit that is specifically designed for your model of chainsaw.

Step 2: Gather your tools

For this repair, you will need a screwdriver, pliers, a socket set, and a nut driver. You may also want to wear protective gear such as gloves and eye protection.

Step 3: Remove the old fuel line

Start by draining the fuel from the chainsaw. Once the fuel is drained, use your tools to carefully remove the old fuel line. You may need to detach any plastic fittings or clamps that are holding the fuel line in place. Be gentle to avoid damaging any other parts of the chainsaw.

Step 4: Install the new fuel line

Take the new fuel line and attach it to the appropriate fittings or clamps. Make sure that the line is securely in place and that there are no leaks. Refer to the instruction manual for your chainsaw if you are unsure about the correct routing of the fuel line.

Step 5: Test the chainsaw

Once you have installed the new fuel line, refill the fuel tank and start the chainsaw to test it. Make sure that the chainsaw is running properly and that there are no leaks from the fuel line. If there are any issues, double-check your work and ensure that all connections are secure.

Fuel line fitting replacement

To replace the fuel line fittings of your Poulan Pro PP5020AV, you will need to follow a few steps. Firstly, it is important to note that fuel lines are subject to failure over time and that today's vehicles have a larger number of lines and a variety of different fittings.

If your fuel line is a nylon line, you will need to purchase a nylon repair kit from an auto parts store. This kit will include two opposing blocks with multiple-sized holes, a gun to hold the blocks, and a nylon-tubing cutter. Here are the steps you can follow:

• Ensure that all sources of ignition are away from the work area to prevent accidental fires.
• Do not use any electric tools when working on a fuel line as this could cause a serious accident.
• Place a drain pan under the area to catch any fuel drips.
• Use wire cutters or a small hacksaw to remove the section of the fuel line that needs to be replaced.
• Install a wood screw into the line to stop further draining.
• Measure the removed piece of the fuel line and purchase the correct size line or fitting, along with a tapered fuel line connector.
• Hold the replacement line in position and mark where to cut.
• Use the nylon line cutter to remove the line.
• Place the ends of the fuel lines into the threaded side of the blocks, allowing a 1/4 inch protrusion.
• Apply a small amount of oil to the tapered connector and place it into one side of the fuel line.
• Squeeze the handle on the tool to bring the blocks together and align the connector with the other end of the fuel line.
• Continue squeezing until the connector is fully seated on all steps of the fuel line. Then, remove the tool.

If your fuel line is a metal line, you will need two tools: a short handheld tubing bender and a tubing cutter. Here are the steps you can follow:

• Place a drip pan under the work area to catch any fuel drips.
• Use a small piece of rubber tubing with a block-off screw to prevent constant dripping.
• Remove the broken fuel line using the tubing cutter, ensuring that you have at least 3 inches of a straight line to install the compression fitting.
• Purchase the necessary length of fuel line and the required number of compression fittings.
• Make any necessary bends for proper fitment.
• Hold the replacement line in place and cut an additional inch off the original line for the compression fitting.
• Separate the parts of the compression fitting.
• Place one perforated cap on the original line with the threads facing out.
• Install the ferrule (ring) over the line in front of the cap.
• Push the original fuel line, ferrule, and cap into the center section of the connector.
• Thread the cap onto the center section of the connector while maintaining pressure on the fuel line to keep it seated.
• Install the cap and ferrule on the opposite end and tighten.
• Turn the key on and check for leaks.

Spark plug installation

To install a spark plug for the Poulan Pro PP5020AV chainsaw, follow these steps:

Firstly, locate the spark plug. It is a small, white and silver component made of steel and ceramic. It is responsible for igniting the air and fuel mixture in the combustion chamber.

Before removing the old spark plug, ensure the chainsaw is switched off and the engine is cool. Once the engine is cool, locate the spark plug wire connected to the plug and carefully remove it. You can do this by gently pulling or wiggling the wire off the plug. Be careful not to damage the wire, as it is essential for the spark plug's function.

Now, use a spark plug wrench or a deep socket wrench to remove the old spark plug. Place the wrench over the spark plug and turn it counter-clockwise to unscrew it. If the spark plug is tight, you may need to apply some force, but be careful not to strip the threads. Once removed, inspect the new spark plug to ensure it matches the old one and is in good condition.

Before installing the new spark plug, check the gap between the centre and side electrodes. The gap should be set to the manufacturer's specifications, which you can find in the owner's manual or online. Adjust the gap if necessary, using a feeler gauge and a gap adjustment tool.

Now, you can install the new spark plug. Screw it into the engine by hand in a clockwise direction until it is snug. Be careful not to cross-thread the plug and ensure it is secure and aligned properly. Once the spark plug is hand-tight, use the spark plug wrench to tighten it further, but be careful not to overtighten it.

Finally, reconnect the spark plug wire to the new spark plug. Ensure it is securely attached and seated correctly. Once the wire is connected, you have successfully installed the new spark plug.
