So your Craftsman chainsaw is not working at the moment even after making sure the fuel tank is full? If you answered yes, then stick with me as throwing your old Craftsman chainsaw away might not be a wise decision and there could be more to it than you can imagine. Read on to learn more.

Chainsaws work at high speeds and therefore generate a large amount of heat. As a result, the fuel lines that are responsible for carrying fuel from the tank to the carburetor can get damaged over time. This would further hinder fuel flow to the engine and prevent it from running again.

But, there’s nothing to stress over when you can change the fuel lines on your Craftsman chainsaw with a simple DIY.

Here is how you can change the fuel lines on a Craftsman chainsaw in simple and easy steps:

A Step By Step Guide to Craftsman Chainsaw Fuel Line Replacement in 2024

To change the fuel lines on a Craftsman chainsaw is now a child’s play. How? Go through the following steps and you’ll know.

But, before that make sure you are wearing gloves as it is an essential part of Craftsman chainsaw manual repair. Without any further delay, let’s get started:

1. Removing fuel

Remove the fuel cap and empty the fuel tank before dealing with the worn Craftsman chainsaw fuel lines.

Also, for storing the fuel, you’ll need an approved storage container and not a random one to prevent hazards.

2. Remove the top cover

Now that you’ve kept aside the extra fuel, it’s time to remove the top cover to access the air filter, carburetor, and fuel lines inside.

For this, take a screwdriver and remove the screws from the cover. Now, you can have a look at the components inside.

3. Removing the air filter

After successfully removing the top cover, the first thing you’ll see is the air filter that needs to be taken out to be able to reach out to the fuel lines.

You can use a screwdriver for this purpose and remove the air filter.

4. Separating fuel filter from the fuel line

When the air filter has been taken out, two thin and thick fuel lines can be seen. One end of the thick fuel line is attached to the carburetor and its other end is with the primer bulb.

Likewise, one end of the thin fuel line is attached to the carburetor while the other end is to a tiny cylindrical fuel filter and is present inside the fuel tank. Pull the fuel line with a wire that has a hooked end and remove the fuel filter from it.

5. Removal of carburetor

Take an appropriate socket driver and remove the bolts that secure the carburetor in its position followed by the removal of the carburetor.

Be gentle when removing the carburetor to prevent gas lines from getting damaged.

6. Dispose of damaged fuel lines

Detach the fuel lines from both sides of the carburetor. You have already removed the thin fuel line from the fuel filter.

Now, only one side of the thick fuel line is left. In the case of a Craftsman chainsaw, this side is connected to the primer bulb.

For the removal of the fuel line, remove the screws of the primer bulb and then simply pull the fuel line with the help of needle-nose pliers.

7. Attach new fuel lines

The most effective way to install new fuel lines is to cut them at an angle with scissors and lubricate them either with water or some oil.

This makes the entering of fuel lines into the fuel tank much easy. Now, push both the fuel lines through the fuel tank and grab them using needle-nose pliers from the mouth of the tank.

After pushing them, cut the angled side of the thin fuel line back to its original shape i.e. circular, and attach it to the fuel filter.

Now shove the filter back into the tank such that it lies at the bottom of the fuel tank. Attach its other side to the carburetor.

Besides, connect the thick fuel line to the primer bulb from one end and with the carburetor from the other end respectively.

8. Reinstalling the carburetor

Secure the bolts and gently place the carburetor back so as not to damage any fuel line which can lead to blockage again.

9. Reinstalling the air filter

Secure the air filter back in its desired space.

10. Re-securing the top cover

Check all the components inside the chainsaw to assure every part is placed in its desired position. When you are done, take the screws and secure the top cover again.

Refill the fuel tank and start the engine to confirm everything is perfectly working. If the engine fires up, the Craftsman chainsaw is all good to go.

Frequently Asked Questions

Does this procedure only apply to Craftsman chainsaws?

No, you can replace the fuel lines of every other chainsaw by following the same steps that we have mentioned above.

The fuel tank of my Craftsman chainsaw is full but the engine is not starting, what could be the cause?

This happens when your fuel lines are damaged causing a blockage in fuel flow. Replace the damaged lines with new ones and the engine will function just fine.

Can I replace the fuel lines all by myself even if I am an amateur?

I don’t think anybody has faced an issue in replacing fuel lines on a Craftsman chainsaw by themselves. However, if you still find any difficulty in getting the job done, you can seek help from a professional.


You are not required to spend extra bucks on buying a new Craftsman chainsaw when you can bring the old one into life by only having to purchase the Craftsman chainsaw fuel line kit which is quite wallet-friendly. This fuel line kit includes fuel lines, a carburetor, an air filter, and some fuel filters.
