I succeeded in replacing the handle for ~$50 while my local VacuFlo dealer said it couldn't be done and wanted to sell me a new hose for $200. That said, the instructions need work (and, better yet, a video). Bigger pictures would help. Also, an exploded view of all the parts would help to see how it all goes together. That might help prevent dummies like me from twisting the collar thereby severing one of the leads. Luckily my son was able to solder it back together and, with a lot of very careful effort, I exposed more of that lead and got it all back together.
