Important Notes

• Verify part number 579645715 before ordering
• Confirm compatibility with your specific Husqvarna equipment model, engine configuration, and fuel tank
• The supplied product information identifies this component as a Tank Cap
• The exact Husqvarna equipment models associated with this tank cap are not identified in the supplied product information
• This listing identifies the component as a fuel tank cap; verify its specific application against the applicable Husqvarna parts diagram before ordering
• Do not assume this cap fits every Husqvarna fuel tank with a similar-looking filler opening
• The exact cap diameter, thread size, thread pitch, sealing configuration, gasket design, venting configuration, material, color, and dimensions are not identified in the supplied product information
• Do not assume the cap is vented or non-vented unless confirmed by the applicable Husqvarna parts information
• Fuel tank venting requirements can be important to proper engine operation; use the specified cap for the applicable fuel system
• Similar-looking fuel caps can differ in thread configuration, sealing surfaces, vent design, diameter, depth, and equipment compatibility
• Do not substitute a generic cap based solely on approximate size, thread appearance, color, or physical fit
• Compare the original cap's part number, dimensions, threads, sealing surface, vent configuration, attachment features, and overall design
• Inspect the associated fuel tank filler neck, threads, sealing surface, gasket area, tank vent system, fuel lines, grommets, and surrounding tank components for wear or damage
• A fuel leak around the cap may result from a damaged cap, seal, filler neck, tank threads, vent system, or fuel tank, so inspect the complete area before replacing components
• If the original cap is difficult to remove or install, inspect the filler neck and threads for damage, contamination, cross-threading, deformation, or corrosion
• If the engine experiences fuel-delivery problems, do not automatically assume the tank cap is responsible; inspect the applicable fuel filter, fuel lines, tank venting, carburetor, and other fuel-system components
• Keep the fuel tank opening and cap sealing surfaces clean and free from dirt, grass, dust, and debris
• Ensure the replacement cap is correctly aligned and fully secured according to the original equipment configuration
• Do not overtighten the cap in a manner that could damage the cap, threads, seal, or fuel tank filler neck
• Do not drill, puncture, cut, enlarge vent openings, modify threads, remove sealing components, or otherwise alter the tank cap to force compatibility or change its venting characteristics
• This listing is for the Tank Cap; do not assume that the fuel tank, fuel lines, filters, grommets, seals, vent components, mounting hardware, or other fuel-system parts are included unless specifically stated
• Shut off the equipment and allow the engine to cool before removing or servicing the fuel tank cap
• Never remove the fuel cap near open flames, sparks, smoking materials, or other ignition sources
• Open the fuel cap carefully if the tank may be pressurized, and avoid spilling fuel onto hot engine or exhaust components
• Use only the fuel type specified by the equipment manufacturer
• Wipe up spilled fuel completely and move the equipment away from the fueling area before starting the engine
• After installation, verify proper cap engagement, sealing, retention, and fuel-system operation
• Inspect for fuel leakage, fuel odor, improper venting, loose fit, damaged threads, or other abnormalities before returning the equipment to normal service.
