This article is about an HV301 - that hose is for a 302. They are different.

Not for the Shark Rocket 301 you didn’t.

The article title says Shark Rocket 301 - those complaining about other models need to learn to read. In any case, in Canada, the hose needed is Canada Tubing Bilge Pump Hose, 1 1/8 Inch Diameter X 6 Ft Length from Home Depot (there’s another brand at Canadian Tire looks exactly the same twice the price).  I left the stiff end on for the upper connection and screwed the other end into the threaded fitting at the other end.  The stiff end slides back and forth as you tilt the head and this relieves the stretch/tear.
