I ordered the coupler and hose assembly because you cannot order just the end. We received the part very quickly, within a couple days. It took my son around an hour to repair. The other comments were helpful about the need to take off top. After taking out the two screws it took a few minutes to figure out we had to slid the top forward for it to completely come off. We also had to take off the dust cover on the bottom in order to twist off the hose. There is also a zip tie inside holding the hose assembly in place. After everything was complete it works great. I hope this info helps.
