Craftsman Lawn Mower Maintenance: Replacing The Fuel Line

If you're having issues with your Craftsman lawn mower, you might need to change the fuel line. This is a common issue, especially if you've left old fuel in your mower, and it's important to know how to fix it. Craftsman suggests that the fuel line be replaced when cracks become visible in the rubber. In this guide, we'll walk you through the steps to safely replace the fuel line on your Craftsman lawn mower and get it running smoothly again.

Locating the fuel line connections

To locate the fuel line connections on your Craftsman lawn mower, you'll need to find the fuel tank and the engine. The fuel tank is usually located under the seat, while the engine is at the other end of the fuel line.

The fuel line connections are where the fuel tank and engine connect to the fuel line. One connection will be on the underside of the fuel tank, and the other will be on the engine. These connections are typically held in place with clamps or spring clips.

To remove the fuel line connection from the fuel tank, squeeze the clamp with pliers and slide it away from the tank. Then, wiggle and pull the fuel line until it comes off. Make sure you have a bucket underneath to catch any fuel that drains from the tank.

The fuel line connection to the engine is removed in a similar way. Again, squeeze the clamp with pliers and slide it away, then wiggle and pull the fuel line to detach it.

It's important to note that the fuel line may have an inline fuel filter, which can be replaced or reused depending on its age and condition. Before beginning any work, ensure the engine is cool and disconnect the wire from the spark plug to prevent accidental starting.

Removing the fuel line from the tank

To remove the fuel line from the tank of your Craftsman lawn mower, you will need a bucket and some standard pliers.

Firstly, locate the fuel line connections. One connection will be on the underside of the fuel tank, and the other will be on the engine. Place a bucket under the connection to catch any fuel that may leak out.

Next, remove the fuel line connection from the bottom of the tank by squeezing the clamp with your pliers and sliding it away from the tank. Then, gently wiggle the fuel line while pulling it until it comes off.

Now, remove the fuel line from the engine connection. This step is the same as the previous one. Squeeze the clamp with your pliers and slide it away from the engine, then wiggle and pull the fuel line until it comes off.

With the fuel line removed from both the tank and the engine, you can now lay it out on the ground. If your fuel line has an inline fuel filter, you can choose to replace or reuse it, depending on its age and condition.

Finally, to separate the fuel line into two pieces, remove the fuel filter by pulling the line off the spigot and releasing the spring clips holding the line to the filter with your pliers.

Removing the fuel line from the engine

To remove the fuel line from the engine of your Craftsman lawn mower, you must first locate the fuel line connections. One connection will be on the underside of the fuel tank, and the other will be on the engine.

Before you begin, ensure that you have allowed the engine to cool completely. Gasoline is highly flammable, so it is important to take the necessary precautions.

Now, to remove the fuel line from the engine connection, you will need to squeeze the clamp on the fuel line with pliers. While squeezing the clamp, gently slide it away from the engine. Then, carefully wiggle the fuel line back and forth while pulling it gently until it comes off the engine connection. Make sure you have a bucket placed under the connection to catch any fuel that may drain from the tank.

Once the fuel line is disconnected from the engine, lay it out on the ground. If your fuel line has an inline fuel filter, you can choose to replace it or reuse it, depending on its age and condition.

After removing the fuel line from the engine, you can proceed to cut new fuel line pieces to match the length of the old pieces. It is important to ensure that the new fuel line is the correct length to avoid any issues during reassembly.

Installing a new fuel filter

Before starting, ensure you have the correct replacement fuel filter for your mower model. You can find this information in your owner's manual or by consulting a small engine specialist. It's also important to work in a well-ventilated area and to avoid any open flames or sparks.

First, locate the fuel line connections on your mower. One connection will be on the underside of the fuel tank, and the other will be on the engine. Disconnect the wire from the spark plug to prevent accidental starting. Drain the fuel tank by placing a bucket under the connection and removing the fuel line from the tank.

Next, remove the old fuel filter from the fuel line. This will result in two separate pieces of fuel line. Take note of the arrow on the filter, which indicates the direction of fuel flow. The new filter must be installed facing the correct direction.

Now, install the new fuel filter onto one of the fuel line segments. Ensure that the arrow on the new filter is facing towards the engine, indicating the correct direction of fuel flow. Push the end of the fuel line onto the spigot of the filter securely.

Reconnect the fuel line to the fuel tank and engine connections. Secure the connections by squeezing the clamps with pliers and sliding them into place. Once the new fuel filter and fuel line are installed, fill the fuel tank and check for any leaks.

It is recommended to replace the fuel filter at least once a year or after each mowing season. Regular maintenance of your lawn mower, including fuel filter replacement, will help ensure optimal performance and extend the life of your equipment.

Checking for leaks

Once you have replaced the fuel line on your Craftsman lawn mower, it is important to check for leaks. Here is a step-by-step guide:

• Before starting, ensure that you have allowed the engine to cool completely. Gasoline is highly flammable, so it is important to take the necessary precautions.
• Fill the fuel tank with gasoline.
• Check the connections you have made to the engine and the fuel tank for any signs of leaks. Pay close attention to the clamps and ensure they are securely in place.
• Start the engine and keep a close eye on your work. If you notice any fuel leaks, immediately stop the engine and turn it off.
• Re-check your connections and ensure that the clamps are tight and secure.
• If you are confident that your connections are secure and there are no visible issues, consult an authorised service dealer for further assistance.

It is important to be vigilant when checking for leaks, as fuel leaks can be dangerous. If you are unsure or uncomfortable at any point, it is recommended to seek professional assistance.
