I didn’t read the other threads, but I replaced a few purge valves under the same condition. Someone finally told me how sensitive it is. DO NOT “top off” or “round up” when filling your tank. When the pump stops, do not add another cent’s worth! I’ve had my ‘08 for 8 years, but I didn’t know about this until about 5 years ago. After replacing 4 valves in 3 years, I haven’t had anymore issues.
