FILTER, FUEL

Fuel filter — sizing & interchange

Yanmar fuel systems are two-stage: a coarse ~30 micron primary water-separator (often a Racor 500FG) and a fine on-engine filter (~10 micron mechanical / ~2 micron common-rail). Never put a finer filter ahead of a coarser one. See the guide for spin-on/element cross-references and Racor element pairing.
