What is the difference between this aftermarket filter and an OEM Yanmar filter?
Our aftermarket filters are engineered to meet or exceed OEM specifications for fit, function, and filtration. They provide a reliable and cost-effective alternative without compromising on quality or performance. See our fixed FAQ on "OEM vs. Aftermarket" for more details.
How often should this fuel filter be replaced?
Replacement intervals depend on engine hours, fuel quality, and operating conditions. As a general guideline, replace the fuel filter element at least once per season or every 100-200 hours of operation, whichever comes first. Refer to your Yanmar engine's service manual for specific recommendations.
What are the symptoms of a failing or clogged fuel filter?
Common signs include engine hesitation, loss of power, stalling, difficulty starting, or rough idling. If you notice any of these symptoms, inspecting and replacing your fuel filter is a recommended first step.
