Keep your Husqvarna riding mower or lawn tractor fueled safely and leak-free with the genuine OEM Fuel Cap Assembly (Part #532179124).

Most Common Reason to Replace: A cracked, stripped, or leaking fuel cap on a riding mower is both a performance and safety issue. A cap that doesn’t seal properly allows fuel to evaporate — reducing efficiency, increasing emissions, and creating a fire hazard from fuel vapor near hot engine components. The integrated gauge lens can also crack, yellow, or become unreadable over time, eliminating the ability to monitor fuel level from the seat. Replacing with this genuine OEM cap assembly restores a perfect seal and a clear, functional fuel gauge in one simple repair.
