I got one of those pumps just the small one for like 6 bucks and put it on my crasftman saw and it works pretty good better than the one that was on it. On mine the hose ran all part of the way down the articulating pipeing, so I ran the new hose all the way down to the end, don't if the dewalt is setup like this or of it has a nipple end on it to put the hose on.
