Note: Very important! This part number is often confused with 4049. The lids physically look similar, but this one is extremely rare. The 0 and 9 are stamped poorly most of the time making some people believe theirs is stamped 4040, when it is actually 4049. The difference is easily to tell by measuring. If your tank is 21 it is this item. If it is closer to 20.25 it is 4049. This item is rare and almost never in stock.
