This filter does not fit the "old model" DWV012 which is about 4 years old. The 9330 filter is 1 inch shorter than the original 9320 filter and the resulting "bottom" on the float cage makes installation impossible. So you'll need to buy a conversion kit, part number 5140174 ($90) or find a 9320 filter. Much luck! The filter is no longer available. Unfortunately, this is a recurring problem with Dewalt, spare or discontinued parts making replacement difficult or impossible without modifying tools or purchasing new ones. The seller should pay attention to this issue to avoid buying a product that does not fit all DWV012 models.
