Conquer Contamination with Water Separator Fuel Filters

Water might seem harmless but it can harm your engine's internal components. Here's how water can sneak its way into your fuel system, and why it's crucial to address this silent enemy:

Condensation: Temperature fluctuations can cause moisture to condense inside your fuel tank, especially during cold weather or after filling up on a humid day.

Gas Stations: While unlikely, microscopic water droplets can be present in even the cleanest fuel tanks at gas stations.

Biodiesel Blends: Biodiesel is hygroscopic, meaning it attracts moisture from the air. This can be a bigger concern for vehicles using higher biodiesel blends.

The Dangers of Water in Fuel

Water doesn't mix well with gasoline or diesel fuel. The presence of emulsified water, which are water droplets suspended within the engine oil, can lead to a multitude of problems for your engine:


Water acts like a rust accelerator, eating away at metal components like fuel injectors, pumps, and engine internals. This can lead to costly repairs or replacements down the road.

Engine Damage

Water can disrupt the combustion process, leading to knocking, sputtering, and a loss of power. In severe cases, water can cause engine components to seize or fail, leaving you stranded and facing significant repair bills.

Poor Performance

Water in your fuel tank can hinder smooth fuel delivery, resulting in rough idling, hesitation, and decreased fuel economy. You'll experience a sluggish engine response and potentially spend more money at the pump due to reduced fuel efficiency.

By understanding the threat of water contamination, you can take steps to protect your engine and ensure a smooth, trouble-free ride.

Benefits of Using Water Separator Fuel Filters

Benefits of Using Water Separator Fuel Filters

Water separator fuel filters are your engine's guardian against the detrimental effects of water contamination. Here's how these filters provide a multi-pronged first line of defence for your vehicle:

Reliable Protection

Water separator filters act as a shield, preventing water from reaching your engine's sensitive components. This safeguards your engine from water-related corrosion, a major cause of internal rust and premature wear. No more worries about expensive repairs or replacement elements due to water damage!

Optimal Performance & Fuel Economy

Clean fuel is the lifeblood of a healthy engine. Fuel water separators ensure a steady flow of clean diesel or gasoline through the fuel lines. This results in optimal engine performance, smoother operation, improved responsiveness, and ultimately, better fuel economy.

Prevents Premature Wear & Tear

Water acts like sandpaper on your engine's internal components. Regular use of a water separator filter prevents these abrasive contaminants from reaching your engine, minimising wear and tear. This extends the lifespan of your engine and ensures reliable operation for years to come.

Long-lasting Engine Reliability

Water separator filters are an investment in your engine's health. By keeping water and other harmful contaminants at bay, you're promoting long-lasting engine reliability. This translates to fewer breakdowns and unplanned downtime, less maintenance hassle, and peace of mind on the road, knowing your engine is well-protected.

Choosing the Right Water Separator Fuel Filter

Not all water separator fuel filters are created equal. Selecting the right one ensures optimal protection and performance for your specific vehicle. Here are some key factors to consider when making your choice:

Fuel Type Compatibility

Water separator filters are designed for specific fuel types. Make sure the filter you choose is compatible with your engine, whether it runs on petrol, diesel, or biodiesel blends. Biodiesel blends may require a filter with additional features to handle the unique properties of this fuel.

Micron Rating

The micron rating indicates the size of particles the filter can trap. A higher micron rating offers finer filtration, removing smaller contaminants, dirt, and other particulates but potentially restricting fuel flow slightly. A lower rating allows for better flow but may not capture the tiniest particles.

Choose a micron rating that balances filtration needs with your engine's fuel flow requirements. Consult your owner's manual or seek guidance from Filters & More's knowledgeable staff for the recommended micron rating for your vehicle.

Flow Rate Capacity

The filter's flow rate needs to match your engine's fuel demands. An insufficient flow rate can restrict fuel delivery, leading to performance issues. On the other hand, an excessively high flow rate might compromise filtration efficiency. Refer to your owner's manual or consult with Filters & More to ensure the chosen filter has the appropriate flow rate for your engine.

Filter Size and Compatibility

Water separator fuel filters come in various sizes and configurations. Ensure the filter you select is physically compatible with your vehicle's designated mounting location. Filters & More offers a wide range of options to fit different vehicle makes and models. You can search by your vehicle details or consult our staff for assistance finding the perfect size and fit.

Don't Let Water Hinder Your Journey

Water contamination can be a hidden threat, silently lurking in your fuel tank and waiting to wreak havoc on your engine. However, with the right water separator fuel filter, you can take control and ensure a smooth, trouble-free ride.

Do I have to drain a fuel/water separator?

Yes, it is important to drain a fuel/water separator as when it gets too full the water will begin to flow into your fuel system which will cause damage such as corrosion. Corrosion will generally occur both on the internal transfer pump and within the system itself which will cause the pump to rust.

How do fuel/water separators work?

A fuel/water separator works by filtering contaminants from the fuel of your vehicle. A fuel/water separator will separate the water away from the fuel which will prevent it from entering and damaging the sensitive areas within your engine.

How often should I clean out a fuel/water separator?

It is recommended to clean out your fuel/water separator every year to avoid the circumstance where it gets too full and you can catch it before the water flows into the fuel system and causes damage. The team at Filters & More can assist you with any questions you may have about the best practices for cleaning your separator.
