Fuel pump filter
Fuel filters are designed to capture impurities, providing a comprehensive defence mechanism for the fuel system. For instance, premium fuel filters, such as the Aeromotive 10-micron fuel filters, offer finer filtration, while their 100-micron fuel filters are suitable for pre-pump applications.
The Can-Am Defender, an all-terrain vehicle, also benefits from efficient fuel and air intake systems. To enhance performance, Can-Am Defender owners can install air intake accessories, such as air filters and intake snorkels, to ensure the vehicle receives clean, pure air. These accessories are particularly useful when riding in challenging environments, such as sandy beaches or snowy terrain, by preventing the intake of dust, water, or other contaminants.
Additionally, Can-Am Defender air intake manifolds and components, including filters and gaskets, are available to prevent dirty air from entering the machine's internals. These accessories can be installed behind the driver's seat, offering an alternative to snorkel systems for moisture protection. Overall, maintaining a clean and efficient fuel system is crucial for optimal vehicle performance, and fuel pump filters play a vital role in achieving this goal.

Air intake accessories
Air Intake Relocation Kits
Some air intake relocation kits require drilling holes in the cab, while others are as simple as using an old sock. Relocation kits can help you move your air intake to a different location, such as behind the driver's seat, to prevent water, dust, or dirt from getting into your air intakes.
Air Intake Pre-Filters
Pre-filters block airborne particulates, such as dust and moisture, without restricting airflow. Companies like Outerwears, SP1, and Helix Racing offer pre-filter products. If you ride in dry and dusty areas, a pre-filter may not be sufficient, and you may need to complement it with a washable air filter, air filter cleaning kit, or air intake degreaser.
Air Intake Filters
Air intake filters ensure that your Can-Am Defender breathes clean air. Washable foam air intake filters are available, which can be reused after cleaning.
Cold Air Intake Kits
Cold air intake kits, such as those offered by Agency Power, improve engine performance by directing cold air to the engine, resulting in greater combustion efficiency and increased horsepower.
Air Intake Manifolds
Air intake manifolds are available to replace the original equipment, ensuring that only fresh, clean, and dry air enters your Can-Am Defender's engine.
Air Intake Adapters and Hoses
Air intake adapters and blow-by hoses are available to ensure compatibility and optimal airflow within the air intake system.
With these air intake accessories, you can maximize the performance of your Can-Am Defender and ensure that your vehicle receives the cleanest air possible, no matter the riding conditions.

Air filter cleaning
Air filters play an important role in the performance of your Can-Am Defender, ensuring the engine receives clean air and maximizing its horsepower and torque. Cleaning your air filter is a simple process and should be done regularly, especially if you ride in dry or dusty areas. Here is a step-by-step guide to cleaning your air filter:
Step 1: Remove the Air Filter
Start by carefully taking out the air filter from its housing. This could be an intake pipe, OE airbox, or custom assembly. Be gentle to avoid damaging the filter media.
Step 2: Tap Off Loose Dirt and Debris
Gently tap the air filter to dislodge any large dirt particles and debris. You can also use compressed air for this step, blowing air from the clean side to the dirty side of the filter.
Step 3: Apply Air Filter Cleaner
Spray a generous amount of air filter cleaner onto both sides of the filter, focusing more on the dirty side. Let the cleaner soak for about 10 minutes. For large filters, you can roll them or soak them in a shallow pan of air filter cleaner.
Step 4: Rinse the Filter
Rinse the filter with cool to warm water (not hot). Always rinse from the clean side to the dirty side to flush out the dirt. You can use a garden hose or your fingers to apply light water pressure. Repeat this step until the water runs clear, free of any dirt or debris.
Step 5: Shake Off Excess Water and Dry
After rinsing, gently shake off the excess water. Allow the filter to dry naturally, or use compressed air to speed up the process. Ensure the filter is completely dry or just slightly damp before reinstalling it.
Step 6: Reinstall the Air Filter
Once the filter is dry, reinstall it into the intake system, airbox, or custom assembly. Follow the original installation instructions provided by the manufacturer.
Additional Tips:
- For extremely dusty conditions, you may need to clean your air filter more frequently and re-oil the clean side of the filter.
- If you prefer not to clean your air filter, you can purchase a replacement air filter and other air intake accessories from specialized retailers.

Fuel tank vent
The fuel tank vent on a Can-Am Defender is an important component of the fuel system. It plays a crucial role in ensuring the smooth operation of the vehicle by regulating air pressure and preventing fuel contamination.
The fuel tank vent is typically located on top of the fuel tank, behind the seat, and can be accessed by removing the rear plastics or the battery tray. The vent lines are made of clear tubing, and the breather, which is white, can be found behind the battery tray. It is held in place by six bolts, and when replacing the breather, it is important to note the directional arrow.
The fuel tank vent is designed with a unique "Y" shape, featuring two check valves, or one-way valves, at each end. These valves serve specific purposes: one valve allows air to enter the fuel tank, while the other releases air pressure from within the tank. This dual-valve system ensures that the pressure inside the tank is equalized, allowing for a smooth and efficient fuel flow.
Over time, the fuel tank vent may require maintenance or replacement. It is recommended to inspect the vent lines and valves periodically, especially when riding in dry, dusty, or sandy conditions. Clogged or damaged vents can impact the performance of your Can-Am Defender. To enhance the ventilation system, Can-Am offers a range of air intake accessories, including air filters, pre-filters, and relocation kits, which can help maximize airflow and protect the vehicle's internals from dirt and moisture.
Additionally, fuel tank vent filters, such as the fuel pump strainer, play a crucial role in preventing fuel system contamination. These filters ensure that impurities are kept out of the fuel pump, prolonging its life and maintaining the overall performance of the vehicle. It is important to replace these filters periodically, as they can become clogged over time, affecting the efficiency of the fuel system.

Frequently asked questions
The fuel tank vent filter is located on top of the fuel tank and behind the seat, behind the battery tray.
First, remove the wires and hose connected to the large serrated ring behind the filler cap. Then, unscrew the cap and carefully lift the whole assembly out of the tank. Finally, install the new filter assembly.
One common issue is that the check valves may be installed in the wrong direction, leading to poor performance. Another issue is that the vent lines may become clogged or restricted, impacting the airflow and causing potential performance issues.
