The manual says to replace with a 9-17816 Filter (Red Stripe), and everywhere I look it's the same filter. So the only thing I can think of is that craftsman changed the nut design. Parts 20 and 21 are the ones that won't fit. If I cut the thread part off parts 20 and 21 will fit properly. As for the hose, I got a craftsman 2-1/2" by 20 foot with universal fittings, unfortunately the fitting for my vac is 1/32" to big, it will go a little bit over half way in before its gets suck. I could force it all the way in but I know it would never come back out.
