Had some laying around from a prior project. But you just need some stuff that the gas won't eat. Since the carb slides over the intake and if you have it seated right, little to no gas should actually touch it, so that might not be an issue. Look to see what rubber hose folks are using to extend their intakes. You will only need a tiny bit. Auto parts or box store would probably cut you an inch for free. Just say you need to check to make sure the diameter is correct and you just need a little bit, should cut you a piece.
