Hose barbs are not included due to the endless methods of mounting. For example 1/2" MPT to Male AN fittings can be used for braided stainless fuel lines. Also 1/2" MPT 90Β°,45Β° or straight barb fittings with various size barbs can be used for rubber hose.
The CAT filters are very nice, well-constructed units, a great upgrade when compared to many OEM filters.
