That is going to be a tough one. I took one to a local NAPA to try to match it up with no luck at all. You will likely have to get a couple pre molded heater hoses and cut a couple and make a splice in the middle to get something to fit right. I would like to ask Fusick if they could look into making these but I don’t think there would be enough demand for it like the radiator hoses.
Thanks Jensen, I have a molded heater hose that would fit, but the rubber used in heater hoses is not resistant to the chemicals in crankcase fumes and would soon rot. I have used silicon hose on supercharger installs so maybe I will look in that direction
