As a vehicle owner, it is important to stay on top of maintenance. One step that often gets overlooked is the fuel tank breather. This small but mighty part plays an integral role in keeping your engine running smoothly and efficiently.
So, let’s look at why you should never skip this simple step when performing maintenance on your vehicle.
What Is a Fuel Tank Breather?
A fuel tank breather is a device that allows air to flow into and out of the fuel tank while maintaining the pressure inside the tank at atmospheric levels. It prevents outside contaminants such as dirt or water from entering the tank and contaminating the fuel inside.
In addition, it helps keep excess vapor pressure from forming in the tank when filling up your car or when driving with a full tank. Without this device, your engine may experience stalling or other issues due to improper air flow and pressure buildup within the fuel system.
Why Is it Important?
A fuel tank breather serves two main functions: first, it allows air to move freely between the outside environment and the inside of the fuel system, providing proper ventilation for your engine.
Second, it filters out any contaminants that might have entered through either side of your car’s fuel system. Contaminants left unchecked can cause serious damage to components like spark plugs and pistons, resulting in costly repairs down the line. Additionally, if not replaced regularly, clogged or worn-out parts can lead to reduced performance and increased emissions.
How Often Should You Replace it?
You should replace this breather every twelve months or twelve thousand miles (whichever comes first). Over time, these parts accumulate dirt and debris which can impede their proper functioning, so make sure that you check it regularly.
Depending on how often you drive your car and what type of terrain you typically cover (e.g., city streets vs off-road), you may need to replace them more frequently than recommended.
