I also installed my new sewer hose this morning! Doing so was a surprisingly big job. I had to cut away the vinyl around the threads of the connector then snip the wire. In theory, I should have been able to just unscrew the connector, but it was in tight. Hooking up the new hose was much easier.
Installing the new hose, which is obviously of better quality, only became a priority today because I needed to dump. Not a fun job, but it needs to be done!
