I install hose protectors without the tool by soaking them in really hot water. It softens them up pretty well. It also works for taking them back off. I personally don't use hose protectors because I agree that they hide the problem rather than prevent them. I have the same hoses that were with the reg when I bought in '98 with no problem. As long as you take care to store them properly they shouldn't kink and cause a problem. I also spray them down now and then with a food grade silicone spray to keep them clean and soft.
