Husqvarn 591375401 Fuel Filter

Clean Fuel, Peak Power: Genuine OEM Husqvarna Fuel Filter

Protect your high-performance 2-stroke engine from the silent killer: contaminated fuel. This Genuine Husqvarna Fuel Filter (591375401) is the factory-original equipment designed to trap microscopic debris before it reaches your carburetor. Engineered for a universal fit across the Husqvarna family of brands—including RedMax, Jonsered, and Poulan Pro—this filter ensures consistent fuel flow and prevents the "lean-run" conditions that lead to catastrophic engine seizure.

Why Genuine Husqvarna Filtration is Non-Negotiable:

• Superior Micron Rating: Unlike generic filters that allow fine silt to pass, this OEM filter uses high-density media to protect sensitive carburetor jets.

• Fuel-Resistant Housing: Constructed from materials that won't degrade or "gum up" when exposed to modern ethanol-blended fuels.

• High-Flow Design: Provides the steady fuel delivery required by large-displacement saws like the 572 XP and 592 XP without restriction.

• Massive Compatibility: Replaces part number 503443201 and fits hundreds of chainsaw, trimmer, and blower models.

🛠️ Mechanic’s Pro-Tip: Don't wait for it to clog! Maintenance Tip: Fuel filters should be replaced at least once per season—more often if you use pump gas with ethanol. If your saw "bogs" when you tilt it to make a felling cut, your filter is likely heavy with debris. Installation Tip: Use a bent piece of wire (a "fuel line hook") to gently fish the fuel line out of the tank. Be careful not to nick the line, or you’ll cause an air leak. Pro-Check: If your fuel line feels stiff or brittle while changing this filter, replace the line immediately to prevent engine damage.
