my 99 came with an elastic cloth plastic lined flex hose. Once while camping I had to use one of wifey’s hair scrunchies to reattach it up top, which was forgotten till the elastic degraded and I found the hose lying while winterizing. So I went along the task of finding a replacement for at least the plastic liner and since I am a DIY idea man , I had many thoughts till one day while helping my sister with her above ground pool I see a piece of used blue drain hose which comes in 2 sizes. The smaller of which she no longer uses ; it stretched over the top side very well , even didn’t need a clamp , but as I was fitting the bottom I found the above mentioned pipe that had slid into the cabinet pipe. While I feel both would do the job , I like the flex b/c my hard pipe is a bit skewed. ; kirby
