What You'll Learn
Fuel smell and fuel cap pressure
If you are experiencing a strong fuel smell in your Can-Am Maverick, there are a few potential causes that you can investigate. One common issue is a blocked or restricted fuel tank vent line, which can cause the tank to build up excessive pressure. This may lead to fuel spraying when the fuel cap is opened and can also result in fuel fumes being pulled into the cabin, causing a strong fuel smell. Check the vent line for any restrictions, such as a kink or pinch, and ensure that it is properly routed and not blocked. If the vent line appears clear, you may need to replace the fuel tank vent filter or the relief valve, as these can become clogged over time.
Another potential cause of a fuel smell is a fuel leak. Check the fuel lines, tank, and filler neck for any signs of leaks or damage. If you notice any wet spots or dripping fuel, tighten the fuel cap and clamps, and replace any damaged or worn seals or hoses. It is important to address fuel leaks promptly to minimise the risk of fire.
In some cases, the presence of a full windshield or windscreen may contribute to the fuel smell, as it can restrict airflow and cause fumes to circulate in the cabin. Removing or opening the windshield for improved ventilation may help reduce the fuel smell.
If you are unable to identify the cause of the fuel smell or if the issue persists after performing basic troubleshooting, it is recommended to consult a dealer or qualified technician for further diagnosis and repair. Do not ignore fuel smells, as they can indicate a potentially serious issue.

Fuel pump replacement
If your Can-Am Maverick is experiencing symptoms such as difficulty starting, a rough idle, or stalling, you may need to perform a fuel pressure test to check for any issues with the fuel pump or fuel system. Before beginning the fuel pressure test, it is important to understand the location and function of the fuel pump in your vehicle. The fuel pump in the Can-Am Maverick is located inside the fuel tank and is responsible for delivering fuel to the engine at the correct pressure.
To perform a basic fuel pressure test, you will need a fuel pressure gauge and a helper. Connect the fuel pressure gauge to the fuel rail schrader valve, which is located on the driver's side of the engine compartment. With the engine off, the fuel pressure should be between 36-45 PSI. Have your helper turn the key to the "On" position, but don't start the engine. Observe the fuel pressure gauge and ensure that the pressure remains steady and does not drop. If the pressure holds steady, it indicates that the fuel pump is likely functioning correctly.
However, if you suspect that your fuel pump may be faulty or if your fuel pressure test indicates low or unstable fuel pressure, you may need to replace the fuel pump. Here is a step-by-step guide on how to replace the fuel pump in your Can-Am Maverick:
- Park your Can-Am Maverick on a level surface and engage the parking brake. Remove the key from the ignition and ensure that the engine is cool before beginning work.
- Disconnect the negative battery cable using a wrench or socket to loosen the terminal nut. Isolating the battery will prevent any accidental sparking during the procedure.
- Locate the access panel for the fuel pump, which is typically located under the rear cargo bed. Remove the cargo bed and any other necessary components to access the fuel pump module. Refer to your owner's manual for specific instructions regarding your model.
- Before removing the fuel pump module, relieve the fuel system pressure and disconnect the fuel lines, electrical connectors, and any other components attached to the fuel pump module. Place a clean cloth around the fuel line disconnect point to absorb any residual fuel and prevent spills.
- Carefully remove the fuel pump module from the fuel tank. This may require lowering the fuel tank or accessing it from below, depending on your model. Take note of the routing of the fuel lines and electrical connections for proper installation of the new fuel pump.
- Obtain a new or rebuilt fuel pump module that is compatible with your Can-Am Maverick model. Ensure that it is the correct part number and that it includes all the necessary components, such as the fuel pump, strainer, and sending unit (if applicable).
- Install the new fuel pump module by reversing the removal process. Ensure that all connections are secure and that the fuel lines are properly seated and tightened to prevent leaks. Reattach any components that were removed to access the fuel pump.
- Reconnect the negative battery cable and tighten the terminal nut securely. Start the engine and check for any leaks around the fuel pump and fuel lines. Also, inspect the fuel lines for proper routing and ensure that they are not kinked or damaged.
- With the engine running, perform a final fuel pressure test to ensure that the new fuel pump is functioning correctly and delivering the specified fuel pressure. Refer to your service manual for the specified fuel pressure values.
- Refill the fuel tank and test-drive your Can-Am Maverick to ensure that the vehicle performs as expected. Pay attention to the engine's performance, acceleration, and overall drivability.
Note: It is always recommended to refer to the Can-Am Maverick service manual for specific instructions and safety precautions when performing any maintenance or repair work. Fuel system repairs can be complex, and it's important to have the necessary tools, knowledge, and skills to complete the job safely and effectively. If you are uncomfortable with any aspect of the procedure, it is best to seek assistance from a qualified mechanic or service center.

Fuel pressure and idle issues
Fuel pressure issues can be caused by a variety of factors, including a faulty fuel pump, a clogged fuel filter, or a blocked fuel line. In this case, the Can-Am Maverick is experiencing fuel pressure and idle issues, which may be related to the fuel cap and venting system.
Symptoms and Causes
The user has noticed a raw fuel smell, particularly on the passenger side, after riding in hot weather and water crossings/mud. Upon inspection, there was pressure built up in the fuel tank, and the vent line that goes into the frame did not seem to be functioning correctly. The high-pitched whistle and fuel smell are likely due to a pinched vent hose, which can be confirmed by inspecting the hose for any kinks or restrictions. This issue is more prominent in desert-like conditions, where the fuel can boil and cause pressure to build up in the tank.
Troubleshooting and Solutions
To resolve the issue, the following steps can be taken:
- Extend the breather hose so it comes out below the skid plate, terminating in the passenger kick panel or near the exhaust. This will help vent the fuel vapors and reduce the pressure build-up in the tank.
- Insulate the fuel tank with adhesive-backed heat insulation foil to reduce the fuel temperature and prevent boiling.
- Reroute the vent hose to a higher location, outside the engine area, to reduce the amount of fuel vapors pulled into the cab.
- Ensure the ride height is correct and adjust the tire pressure to the recommended PSI for your terrain. This will improve handling and reduce tire wear.
- Replace the fuel pump if it is faulty or making unusual noises. The fuel pump may be failing if the engine is hard to start or surging.
By following these steps and making the necessary adjustments, you can resolve the fuel pressure and idle issues with your Can-Am Maverick. It is important to regularly inspect and maintain your vehicle, especially after riding in harsh conditions, to prevent further complications and ensure a smooth riding experience.
