Yanmar 104500-55710 Fuel Filter for Small Diesel Engines (1GM, 2GM, 3GM Series)

The Yanmar 104500-55710 is the standard small fuel filter used in numerous compact Yanmar diesel engines, commonly found in sailboats and auxiliary craft. This filter element is designed to fit perfectly in the engine’s original filter bowl/sediment trap. During operation, diesel fuel can carry tiny particles from the tank or traces of water – the 104500-55710 filter catches these contaminants before they reach sensitive components like the fuel pump or injectors. By doing so, it prevents clogs, uneven engine performance, or more serious damage. Replacing this filter is part of routine engine maintenance – for Yanmar GM series, inspection and change are recommended every 100 hours or yearly. The procedure itself is straightforward: shut off the fuel valve, loosen the sediment bowl bolt, carefully remove the old filter and O-ring, clean out the bowl, insert the new filter and gasket, then reassemble and secure. Be sure to bleed any air from the fuel system after replacement. With this genuine Yanmar filter, your engine will start more easily and run smoothly even if the fuel quality is not perfect.

Use Cases & Recommendations (EN):

• Suitable for small Yanmar diesel engines (single-cylinder ~9 HP, twin-cylinder ~15–18 HP, triple-cylinder ~27–30 HP) typically powering 20–30 ft sailboats, pocket trawlers, or serving as auxiliary generators – ensures reliable performance during extended voyages
• Regularly replacing this filter is especially crucial for sailing yachts, where fuel might sit in tanks for long periods – accumulated condensation and sludge can clog the system. Installing a fresh filter before a long passage guarantees peace of mind and trouble-free running at sea
