They actually sell these on Summit, but they are about a month to ship. So I got some 5/8” I.D. fuel line hose, thin film of grease on tube, heated hose with heat gun and it went on. Not that easy, but it’s on and will not need clamps, it’s TIGHT! Obviously, for rest of its connections, will get clamps.
