Parts Desk Insights
Best use case: This is the correct replacement fuel filter for D3 series engines at every scheduled service interval. It’s also the right part when troubleshooting fuel starvation, rough running, or hard starting on a D3 — a clogged or water-saturated filter is one of the first things to check. Using the genuine OEM filter ensures the correct micron rating and bypass valve specification for your engine’s fuel system.
Common issues: D3 owners frequently encounter water contamination in the fuel system, particularly in boats that sit for extended periods or are used in areas with lower-quality diesel. A filter that’s past its service interval can restrict fuel flow enough to cause power loss or rough running at higher RPM. Customers sometimes overlook the fuel filter when chasing injector or lift pump issues — it’s always worth replacing the filter first.

Service Interval
Replace the fuel filter at every annual service or every 250 operating hours, whichever comes first — or sooner if fuel quality is suspect or the engine shows signs of fuel starvation. Consult your Volvo Penta D3 service manual for the interval specific to your engine’s operating conditions.
Technical FAQ
Q: Does 21139810 fit all D3 variants?
A: It is commonly used across the D3-110 through D3-220 range, including A and I variants. Always verify using your engine serial number and the Volvo Penta parts diagram, as filter specifications can vary by production run.
Q: What do the cross-reference numbers SN30052 and SK48997 mean?
A: These are equivalent part numbers from aftermarket filter suppliers (HIFI Filter and others). The Volvo Penta OEM part 21139810 is the factory-specified replacement and is recommended to ensure correct fit and filtration performance.
Q: Is this a genuine OEM filter?
A: Yes. This is a genuine Volvo Penta OEM fuel filter, not an aftermarket substitute.
Q: How do I know when the fuel filter needs replacing?
A: Common signs include hard starting, rough running at load, reduced top-end power, or a fuel filter warning on the engine display. Replace at the scheduled interval regardless of symptoms.
