Important Notes

• Verify part number 576403703 before ordering
• Confirm compatibility with your specific Husqvarna equipment model and fuel tank configuration
• This component is identified as a tank cap; verify that your equipment requires this exact part number before ordering
• The exact cap diameter, thread size, thread pitch, material, color, sealing configuration, venting design, pressure characteristics, and compatible fuel tank specifications are not identified in the supplied product information
• The supplied information does not identify whether this cap is vented or non-vented; do not substitute one type for another without confirming the requirements of the equipment
• Compare the original cap’s diameter, thread or locking interface, sealing surface, overall profile, venting configuration, and tank-opening fitment
• Do not substitute a fuel tank cap based solely on approximate diameter, appearance, or the ability to physically attach to the tank
• Inspect the associated fuel tank filler neck, threads, sealing surfaces, tank opening, vents, seals, gaskets, fuel lines, fittings, and surrounding fuel-system components for wear or damage
• Check the filler neck and cap interface for cracks, damaged threads, deformation, corrosion, contamination, or other conditions that could prevent proper sealing
• A damaged, loose, incorrectly fitted, or improperly vented fuel cap may contribute to fuel leakage, fuel contamination, fuel odors, or fuel-system operating issues
• Keep the fuel tank opening clean and prevent dirt or debris from entering the tank while the cap is removed
• Do not overtighten the cap or force it onto incompatible or damaged threads
• Replace any required sealing component if it is worn, hardened, cracked, distorted, or otherwise unable to provide proper sealing
• This listing is for the tank cap; do not assume that gaskets, seals, fuel lines, fittings, vents, valves, filters, tank components, or additional hardware are included unless specifically stated
• Shut off the engine and allow it to cool before opening or servicing the fuel tank
• Keep fuel, fuel vapors, sparks, flames, cigarettes, and other ignition sources separated during fuel-system service
• Clean up any spilled fuel immediately and do not operate the equipment if a fuel leak is present
• After installation, verify proper cap fitment, engagement, sealing, tank closure, leak-free operation, and overall fuel-system function before returning the equipment to normal service
