If you're having trouble getting your Arctic Cat to start, you may need to prime the fuel line. This process can vary depending on the model of your Arctic Cat and the specific issues you're facing, but there are a few general methods that are often effective. One common approach is to pressurize the gas tank by blowing into the vent tube or using an air gun to force air into the fuel tank, which can help to push gas through the fuel line and into the carb. Another option is to remove the fuel lines from the carbs and use a syringe to fill the bowl, which can help prime the line. In some cases, you may need to replace the fuel pump or check for issues with the fuel filter or intake line.
| Characteristics | Values |
|---|---|
| Fuel pump issues | The fuel pump may not be powerful enough to prime the system when it is dry. |
| Excessive pulling | The fuel pump's inability to prime the system can lead to excessive pulling of the starter rope, causing aggravation, frustration, and sore arms, shoulders, and hands. |

What You'll Learn
Blowing into the vent tube
To begin, locate the vent tube on your Arctic Cat. This is usually found near the fuel tank, often close to the fuel fill opening. Once you have identified the vent tube, you can start the process of blowing into it. It is recommended to have the gas cap on while performing this task.
Cover the vent tube with your mouth and blow air into it. To maintain pressure, hold your finger over the vent while taking another breath. It should take no more than three breaths to complete this process, and you will need to keep your finger in place to ensure the gas flows into the carb. The more gas in the tank, the easier it will be to blow into the vent tube and create the necessary pressure.
While blowing into the vent tube, you are essentially filling the float bowls with air. This action can help to prime the fuel system and get fuel to the carbs. However, it is important to note that this method does not guarantee fuel will reach the bottom end, and additional steps may be required to get the atomized fuel through the motor to the top of the piston.

Using a syringe to fill the bowl
If you are experiencing issues with your fuel line on your Arctic Cat, one method to prime the fuel line is by using a syringe to fill the bowl. This method is useful when you have drained your fuel tank and the fuel is not flowing through the line.
Firstly, pull the lines off the carbs, ensuring that the gas cap is on. Then, take a syringe and fill the bowl with fuel. The fuel line will then prime itself. This method has proven successful for some Arctic Cat owners, with their vehicles firing up after a few pulls.
It is important to note that this method may not work for all models of Arctic Cats, and there are other ways to prime the fuel line. For example, some users have reported success by blowing into the vent tube or fuel tank vent line to pressurize the gas tank, which can help the fuel flow into the carb.
Additionally, it is worth checking the fuel pump and the impulse line from the crankcase to the pump, as a faulty fuel pump or a blockage in the line could be preventing the fuel from reaching the carb. If the fuel pump is not working, you may need to replace it or try other methods such as pressurizing the tank or using an air gun to prime the system.
Overall, using a syringe to fill the bowl is a straightforward method to prime the fuel line on an Arctic Cat. By following the steps outlined above and making sure the gas cap is on and the lines are off the carbs, you can effectively prime the fuel line and get your vehicle running smoothly again.

Priming the fuel pump
To prime the fuel pump of an Arctic Cat, you need to ensure that there is no air in the fuel line. This can be done in several ways.
One method is to blow into the fuel tank's vent tube. This can be done by holding a finger over the vent while blowing, to maintain pressure. With enough pressure, the gas will flow into the carb. This method is most effective when the gas tank is at least half full.
Another method is to pressurize the gas tank by drilling a hole through a tennis ball, inserting an air gun into one end, and placing the other end over the fuel fill opening. This will pressurize the tank and prime the fuel system.
If you suspect that the fuel pump itself may be faulty, you can test it by performing the following steps:
- Take the fuel lines off.
- Remove the spark plug wires.
- Turn off the ignition and kill switch.
- Grab the primary clutch and turn it back and forth.
- Check if gas comes out of the fuel lines.
If gas does not come out, the issue may lie with the impulse line from the crankcase to the pump, or with the fuel pump itself.

Drilling a hole through a tennis ball
To prime the fuel line on an Arctic Cat, one method is to blow into the fuel tank vent line. This can be done by blowing into the vent tube and holding your finger over the vent to maintain pressure. Another method is to pressurize the gas tank, which can be done by drilling a hole through a tennis ball and inserting an air gun into one end, with the other end over the fuel fill opening. This will prime the fuel system in a few minutes.
Now, to drill a hole through a tennis ball, you will need a few tools and a steady hand. Here is a step-by-step guide:
- Wear protective gloves: It is important to protect your hands when handling sharp tools and the tennis ball, which may have a slippery surface.
- Choose the right drill: A handheld power drill with a diamond-coated hole saw drill bit is ideal for this task. This type of drill bit is designed for cutting through tile and ceramics but also works well on tennis balls. It provides a clean cut without requiring additional equipment.
- Stabilize the tennis ball: Place the tennis ball in a medicine cup or hold it firmly against a solid, knife-safe surface, such as a cutting board. Ensure the rounded edge of the seam faces up, and use your ring finger and pinky to support the back of the ball to prevent it from rolling away.
- Mark the drilling spot: Use a marker to indicate the spot where you want to drill the hole. This will help you align the drill bit accurately.
- Drill slowly and steadily: With your non-dominant hand, hold the ball firmly as described in step 3. With your dominant hand, start the drill slowly and apply gentle pressure. Keep the drill bit straight and maintain a steady speed to avoid tearing or uneven cutting.
- Remove the ball from the cup: Once the hole is drilled, carefully take the ball out of the medicine cup, if you used one, and inspect the hole.
By following these steps, you should be able to successfully drill a hole through a tennis ball, which you can then use for priming the fuel line on your Arctic Cat or for other creative projects.
