I havn't had to replace mine, but you may find a suitable rubber pipe coupler(rubber sleeve with 2 hose clamps) at the local hardware plumbing department. They come in different sizes, and even in adapter sizes to join different sizes of pipe...
Ron I thought of that, however the rubber on the tractor is about 7 inches long. I have never seen any in the plumbing dept. that long . There is a Northern tool close to where I live . I may have to order from them . I wanted something made from a little heavier material though. Robby
Take the two sections to the hardware and buy a rubber pipe coupler as suggested. The one slides inside the other so you only need a few inches of rubber on each section to hold the hose clamp. I know I did this a few years back on a Jinma that had a fuel leak that caused the rubber to swell to twice its size and it worked great.
The coupler I bought was different sizes on both ends and both sides fit like that was what it was made for!
