Fuel Filters

Clean Fuel. Reliable Power. Proven Protection.

Keeping fuel clean is critical to engine performance, emissions compliance, and long-term reliability. Yanmar Genuine Fuel Filters are engineered to prevent water, dirt, and fine contaminants from reaching precision fuel system components.

Manufactured to strict Yanmar factory standards, each filter delivers consistent filtration efficiency, a long service life, and reliable protection under real-world operating conditions – the result: stable engine performance, lower emissions, and reduced risk of unplanned downtime.

Choose Yanmar Genuine Fuel Filters to protect your engine investment: every hour, every job.

Protection Starts With Clean Fuel

Yanmar Genuine Fuel Filters maintain high filtration efficiency over time, keeping contaminants out of your engine where they cause wear and breakdowns.

As particles accumulate, clogging stays low, so your engine breathes cleaner fuel longer, runs smoother, and lasts longer through every service interval. That means fewer filter changes, less downtime and more uptime for the work that matters.

Engineered Inside Out

Every Yanmar Genuine Fuel Filter is designed as a critical component for engine protection. Each internal element has a clear function and a reason to be there.

  1. Plated top & outer housing
    Resists corrosion caused by water and moisture, protecting the filter structure and preventing long-term degradation.
  2. Double-edged sealing design
    Ensures a secure, deformation-free seal, significantly reducing the risk of fuel leakage under vibration and pressure.
  3. Reinforced perforated plate
    Provides structural strength and stable fuel flow, even under high filtration pressure and demanding operating conditions.
  4. High-density microfibre filter paper
    Double-edged filter media captures contaminants down to 1 μm, maintaining high filtration efficiency and long service life.

The result: consistently clean fuel, stable engine performance, and reliable protection. Precisely as engineered by Yanmar.

Precision You Can See. Protection You Can Trust.

Controlled Micro-Fibre Structure

Yanmar’s high-density micro-fibre filter media uses uniformly distributed fibres to create a precisely controlled pore structure. This enables contaminants to be captured throughout the depth of the media, not just on the surface resulting in consistently high filtration efficiency down to 1 μm.

Higher Efficiency Over Time

Because contaminants are evenly distributed throughout the filter media, flow resistance increases more slowly, reducing clogging. The result is stable fuel flow, sustained filtration performance, and longer service life as clearly demonstrated by the higher efficiency curve compared to non-genuine filters.

Why should I use Yanmar genuine fuel filters instead of aftermarket filters?

Yanmar Genuine Fuel Filters are engineered specifically for Yanmar engines and fuel systems. They provide controlled filtration down to 1 μm, protect against water-induced corrosion, and maintain stable fuel flow under high pressure, something non-genuine filters are not designed or tested to guarantee.

What happens if fuel filtration is not good enough?

Inadequate fuel filtration allows dust, water, and fine particles to enter the injection system. This can cause premature wear of injectors and pumps, poor starting behaviour, loss of engine power, increased emissions, corrosion, and a higher risk of fuel leakage or unplanned downtime.

How fine is the filtration of Yanmar genuine fuel filters?

Yanmar Genuine Fuel Filters use high-density micro-fibre filter media that captures contaminants as small as 1 micron (μm). This level of filtration is essential for modern high-pressure diesel injection systems, where even microscopic particles can affect performance and durability.

Do Yanmar genuine fuel filters last longer than non-genuine filters?

Yes. Thanks to their depth-filtration micro-fibre structure, contaminants are distributed evenly throughout the filter media. This reduces clogging, maintains fuel flow for more extended periods, and delivers a longer, more predictable service life than conventional filter designs.

Can non-genuine fuel filters affect engine reliability and emissions compliance?

They can. Poor filtration efficiency and inconsistent material quality may lead to unstable injection performance, higher wear rates, and increased emissions. Using Yanmar Genuine Fuel Filters helps ensure the engine operates exactly as designed, reliably and efficiently, and in line with emissions requirements.
