The Yanmar 41650-502330-12 is a genuine OEM fuel filter / water separator assembly for select Yanmar marine diesel applications. Current parts references identify it as FILTER, FUEL D90, and current Yanmar dealer references show it as the assembled fuel filter / water separator service part used on compatible engines.
Current fitment references support use on select Yanmar 6LY2, 6LY3, and 6LYA marine diesel applications, including 6LY2(A)-STE(P), 6LY3-UTP, 6LY3-STP, 6LY3-ETP, 6LYA-UTE, and 6LYA-STE. Additional Yanmar references also tie the related D90 filter family to other Yanmar marine engines, but the strongest direct support for 41650-502330-12 is the 6LY2 / 6LY3 / 6LYA group.

When This Part Needs Replacement

Parts Desk Insight
Fuel filtration is especially important on Yanmar common-rail and high-performance diesel platforms because the fuel system is far more expensive than the filter servicing it. Replacing the correct OEM D90 assembly on schedule is a simple preventative-maintenance step.
