Replacing Fuel Line On Echo Chainsaw: Step-By-Step Guide

If you're looking to replace the fuel line on your Echo chainsaw, there are a few steps you'll need to follow. Firstly, it's important to remove all the fuel from the tank. You'll then need to remove the hose from the tank to the carburettor. It's recommended that you take the old hose with you when purchasing a new one to ensure you get the correct replacement. When installing the new fuel line, you'll need to splice one end of the fuel line with scissors to help guide it into the hole more easily. This process can be slightly technical, but once you've got a hold of the line from the other side, it will be easier to pull it through.

Prepare your chainsaw

To prepare your chainsaw for a fuel line change, it is important to ensure that the chainsaw is switched off and completely cold. Place the chainsaw on a flat surface, preferably a table at waist height, to avoid back strain. Remember to wear protective gloves and safety gear to protect yourself from injury.

Next, remove the old fuel from the chainsaw. Use an old container to empty the fuel tank and keep it nearby. The old fuel can be used to clean accumulated dust and debris from the components that will be removed later in the process.

Now, remove the cylinder cover and air filter. Use a screwdriver to remove the nuts holding the cylinder cover in place. Most chainsaw models have three to four nuts. Once the nuts are removed, carefully lift off the cover and take out the air filter. Check if the air filter can be cleaned and reused, or if it needs to be replaced. If it is dirty and no longer functional, it is recommended to replace it with a new one. Additionally, disconnect the spark plug to ensure there is no accidental ignition during the fuel line replacement process.

At this stage, your chainsaw should be prepared for the next steps in changing the fuel line. Remember to keep your work area well-ventilated and to follow safety precautions when working with tools and equipment.

Remove the old fuel

To remove the old fuel from your Echo chainsaw, you will need to place your chainsaw on a flat surface, preferably a table at waist height. Ensure that you are wearing work gloves and that your chainsaw is switched off and cold.

Grab an old container and empty the old fuel from the gas tank into it. Keep this container close by, as you can use the old fuel to remove any accumulated dust and debris from the components that you will be removing in the next steps.

Next, you will need to remove the cylinder cover and air filter. Using a screwdriver, remove all the nuts on the cylinder shield. Most Craftsman chainsaw models have 3-4 nuts on the shield. Once the nuts are off, you can remove the cover and take out the air filter. Check if the air filter can be cleaned and placed back in, or if it needs to be replaced. You might also need to replace the fuel filter if it is dirty and not working properly. Additionally, disconnect the spark plug.

Now, you can move on to removing the air filter housing. Remove the two bolts holding the air filter housing in place and carefully inspect the throttle linkage attached to the backside of the air filter housing. Take a picture of the arrangement with your phone, as this will help you remember how to reassemble everything correctly later.

At this point, your chainsaw should be ready for the new fuel line to be installed. However, before installing the new fuel line, it is important to clean or replace the carburetor if necessary.

Remove the cylinder cover and air filter

To remove the cylinder cover and air filter of your Echo chainsaw, follow these steps:

Firstly, get an appropriately-sized screwdriver and remove all the nuts on the cylinder shield. Most Craftsman chainsaw models come with 3-4 nuts on the shield. Once these nuts are off, you can carefully lift off the cylinder cover.

Next, take out the air filter. Check if it can be placed back once you have washed it with fuel. If it is dirty and unusable, you will need to replace it with a new one.

Finally, disconnect the spark plug.

Remember to keep all the nuts and bolts in a container so that you don't misplace them.

Remove the carburetor

To remove the carburetor of an Echo chainsaw, you must first prepare your workspace and the chainsaw. Place the chainsaw on a flat surface at waist height, such as a table, and ensure you are wearing work gloves for safety.

Next, remove the fuel from the chainsaw's tank by emptying it into an old container. Keep this container close by, as you can use the old fuel to clean the inside of the components you will be removing.

Now, remove the cylinder cover and air filter. Use a screwdriver to remove the nuts on the cylinder shield, then take out the air filter. Check if the air filter can be cleaned and replaced, or if it needs to be replaced entirely. You may also need to replace the fuel filter if it is dirty. Additionally, disconnect the spark plug.

With the air filter removed, you can now access and remove the carburetor. First, pull the carburetor to the side and remove the fuel lines and vent lines with a flathead screwdriver. If the connections are rigid, use WD-40 to loosen them. Once the fuel and vent lines are removed, you can easily pull the carburetor out.

Install the new fuel line

To install the new fuel line, you will need to purchase a manufacturer-approved fuel line. While a standard fuel line will work, it is recommended to use company-approved components to ensure optimal performance.

Once you have the new fuel line, use scissors to splice one end. This will make it easier to feed the line into the hole. Carefully feed the fuel line into the hole, as this step can be slightly technical. Once you have a hold of the line from the other side, it will be easier to pull it through.

Compare the new fuel line with the old one to get an idea of how much pipe you need to insert into the carburetor. Ensure that you have enough length of the line on the other side to attach the fuel filter. Once you have attached the pipe to the carburetor and the primer bulb line, you can attach the fuel line to the fuel filter before placing it inside the fuel tank.

Now, place the carburetor back in its position, ensuring that it fits perfectly on the studs. Then, attach the throttle linkage on the backside of the air filter housing. Refer to the photos you took earlier of the original arrangement to ensure that everything is connected correctly. Put the air filter housing back in place and tighten the bolts.

If everything is placed correctly, you should not need to force anything when fitting the housing. Place the air filter in its position and connect the spark plug. Finally, screw down the cylinder shield, ensuring that you remove any oil, dust, or grease inside the shield and air filter housing.
