i second the summit idea, they carry the hose that we used to use on gas turbine engines while i was in the navy, super durable hose, it has an orange silicone outside with steel layer, then another layer of silicone on the inside iirc. you could also check ebay, i had a drain hose problem, it was kinking and not allowing flow, i found some marine hose that had wire coiled inside the rubber to preven kinks, worked great too.
