Start by identifying the fuel tank on your Arctic Cat. It is usually located beneath the vehicle, and you might need to access it by removing some panels or covers. Once you've located the tank, find the drain plug, which is typically a small opening at the bottom of the tank. Place a suitable container under the drain plug to catch any fuel that drains out.

Step 2: Drain Old Fuel

Now, carefully remove the drain plug and allow the old fuel to drain into the container. This process might require some patience, especially if the fuel has been sitting in the tank for a while. As you drain, you may notice some sediment or water separating from the fuel. This is normal and should be caught in the container. If the fuel pump primer is required, it's a good indication that the fuel system needs a thorough flush.

Step 3: Using a Fuel Pump Primer

A fuel pump primer is a handy tool for this task. It helps to prime the fuel system and ensure that the pump is functioning correctly. Here's how to use it:

• Locate the fuel pump, which is usually connected to the fuel lines.
• Attach the primer to the fuel pump's inlet line.
• Press the primer's trigger to prime the pump. This action will force fresh fuel into the system, priming the pump and the lines.
• Hold the trigger for a few seconds to ensure the pump is fully primed.
• Release the trigger and check for any fuel flow.

Step 4: Reassemble and Test

Once you've drained the old fuel and primed the system, carefully reassemble the fuel tank and secure it back in place. Ensure all connections are tight and secure. Start the engine and let it run for a few minutes. Check for any unusual noises or vibrations, and observe if the engine is running smoothly. If everything is in order, you've successfully removed old fuel and primed the fuel line on your Arctic Cat.

Cleaning: Clean lines with a fuel line cleaner to remove contaminants

To ensure your Arctic Cat's fuel lines are in optimal condition, it's crucial to clean them regularly. Over time, fuel lines can accumulate contaminants such as dirt, moisture, and varnish, which can lead to reduced performance and potential engine issues. Cleaning the fuel lines is a straightforward process that can be done at home with the right tools and products.

Start by disconnecting the fuel line from the fuel tank and the engine. This step is essential for safety and to prevent any spills. You can use a fuel line disconnect tool to make this process easier. Once disconnected, use a fuel line cleaner to remove contaminants. There are various types of fuel line cleaners available, including chemical-based and solvent-based options. Chemical-based cleaners are typically more effective at dissolving contaminants, while solvent-based cleaners are better at removing stubborn deposits. Choose a cleaner that is compatible with your fuel line material to avoid any damage.

When applying the cleaner, ensure you follow the manufacturer's instructions. Typically, you will need to spray the cleaner directly into the fuel line and allow it to sit for a specified amount of time to dissolve the contaminants. After the recommended dwell time, rinse the fuel line with a clean, dry cloth or a low-pressure air gun to remove the cleaner and any dislodged contaminants. It's important to ensure that no cleaner remains in the fuel lines, as it can attract moisture and cause corrosion.

For best results, repeat the cleaning process a few times, especially if the fuel lines are particularly dirty. This will help ensure that all contaminants are removed, and the fuel lines are in top condition. After cleaning, always reconnect the fuel lines securely and test the engine to ensure there are no leaks or issues.

Regular cleaning of the fuel lines is a simple yet effective way to maintain your Arctic Cat's performance and longevity. By taking the time to clean the fuel lines, you can prevent potential issues and ensure your vehicle runs smoothly and efficiently.

Priming Method: Use a hand primer or a fuel pump to introduce air into the lines

To prime the fuel lines on your Arctic Cat, you can use a hand primer or a fuel pump, which is a practical and effective method to ensure the engine receives the necessary fuel. This process involves introducing air into the fuel lines to create a vacuum, allowing the fuel to flow into the engine. Here's a step-by-step guide on how to do it:

Start by ensuring your Arctic Cat is in a vertical position, with the fuel tank empty. This is crucial to prevent any fuel from entering the engine during the priming process. Locate the fuel lines, which are typically connected to the fuel pump and the carburetor. You might need to remove some panels or access panels to get to the fuel lines, depending on your Arctic Cat model.

Now, you can use a hand primer or a small fuel pump. For the hand primer, place the end of the primer into the fuel line and squeeze the handle to introduce air. Hold the primer in place for a few seconds, then release the handle. This action will create a temporary vacuum, drawing air into the fuel line. Repeat this process a few times to ensure a good priming effect. If you have a fuel pump, attach it to the fuel line and activate it to pump air into the system.

When using a hand primer or fuel pump, it's essential to maintain a steady and consistent action. Apply enough force to create a noticeable vacuum but be careful not to overdo it, as excessive force might damage the fuel lines. The goal is to create a controlled environment that allows the fuel to flow freely into the engine once the priming process is complete.

After priming the fuel lines, allow the engine to rest for a few minutes. Then, start the engine and let it run for a while. You should notice that the engine is now receiving fuel and is running smoothly. If you encounter any issues, such as a lack of fuel flow or engine misfires, you might need to repeat the priming process or inspect the fuel lines for any blockages or damage.
