Thanks Bob. Gates and Goodyear do make silicone hose but would have to make a connection pipe to hook up to the Rad, Industrial Metal in Riverside said they can make the pipe bends with no problems so just the ends of it would be the silicone. I have already made the heater hose out of silicone on our trucks we added a coolant filter and fabed the filter into the system there. Your correct no pre fab hose from either company.
