Having a properly functioning chainsaw is essential for cutting and trimming trees and branches quickly and efficiently. However, over time the fuel lines in your Poulan chainsaw can become cracked, brittle, and develop leaks. Replacing old worn out fuel lines with new ones can seem daunting, but is actually a straightforward process that anyone can complete themselves. In this guide, I will walk through the importance of fuel line replacement, what’s involved in the process, and provide a step-by-step tutorial for replacing fuel lines on a Poulan chainsaw. Fuel lines play a crucial role in delivering gasoline from the fuel tank to the carburetor where it can be mixed with air. When the fuel lines become damaged, it interrupts this fuel flow causing issues with the chainsaw’s performance. Common problems from deteriorating fuel lines include the chainsaw not starting, sputtering or dying after starting, lack of power, and leaks near the carburetor. Replacing the lines before they get to this failing state is key to keep your Poulan chainsaw running optimally.

Once you have everything ready, follow these steps:

Preparing the Chainsaw

First you need to access the fuel lines by removing some parts of the chainsaw housing:
  • Locate the fuel cap and drain the gasoline from the fuel tank into a small bowl
  • Find the spark plug wire and disconnect it from the spark plug
  • Use a screwdriver to remove the screws holding the air filter housing in place
  • Lift off the air filter housing
With the housing removed you can now see the fuel lines running from the carburetor to the fuel tank.

Removing the Old Fuel Lines

  • Locate where the fuel lines connect to the carburetor and fuel tank
  • Use needle nose pliers to pinch the fuel line ends and gently wiggle and pull to detach them from their fittings
  • Remove the old fuel lines from the chainsaw
  • Use a rag with isopropyl alcohol to clean the areas where the lines connected
Be careful not to bend or damage the small carburetor fittings when removing the old fuel lines.

Installing the New Fuel Lines

Your replacement kit should come with directions showing where each specific line routes on your model. Follow their diagram closely when connecting the new lines.
  • Take the end of the first new fuel line and push it onto the corresponding carburetor fitting
  • Pinch the line with pliers and tug gently to ensure it is tightly attached
  • Run the line through the retaining clips or guides along the route back to the fuel tank
  • Push the other end of the line onto the fuel tank fitting and secure with pliers
  • Repeat with the second new fuel line
Make sure the new fuel lines follow the same path as the old lines. Refer to the instructions and diagram to verify correct installation. The lines may have arrows showing the direction of fuel flow.

Securing the New Fuel Lines

Once connected on both ends, inspect the new fuel lines. Make sure they are securely in place and the fittings are tight.
  • Check that the lines are not sagging and have tension rather than slack
  • Make sure the lines are properly seated in any retaining clips or guides along their path
  • Tug gently on the ends to confirm they are tightly attached

Tips for Maintaining Fuel Lines and Chainsaw Performance

To maximize your chainsaw’s lifespan and performance, follow these maintenance best practices:

Regular Inspection and Cleaning

  • Check fuel lines before each use for cracks or leaks. Look for sagging lines or damaged connections.
  • Clean the fuel line ports on the carburetor and fuel tank periodically using compressed air or pipe cleaners to remove residue buildup.
  • Use a rag dampened with isopropyl alcohol to wipe down the outside of fuel lines and fittings to prevent dirt or sawdust clogs.

Replacing Fuel Lines as Needed

  • Replace fuel lines every 1-2 years or as recommended for your model. Don’t wait for complete failure.
  • Use fuel line kits made specifically for your chainsaw make and model. Using universal parts can cause poor fit and leaks.
Following the manufacturer’s maintenance guidelines for your particular Poulan or other brand chainsaw is important. Well-maintained fuel lines and regular cleaning of the oiling system pieces will keep your chainsaw’s engine and bar functioning properly season after season.

Can I Use the Fuel Mix I Made for My Poulan Chainsaw to Mix Chainsaw Gas for Other Brands?

Mixing chainsaw gas for different brands may seem convenient, but it can have adverse effects. Each brand may have specific fuel mix requirements for optimal performance and engine longevity. Deviating from the recommended fuel mix ratio can lead to engine damage, reduced power, or decreased overall efficiency. To ensure safety and protect your equipment, it’s always best to use fuel mixes specifically designed for the chainsaw brand you are using.
