I have a vehicle where a system associated with the PCV valve is heated (heat-traced?) by a slipstream of coolant taken from the upstream heater core nozzle, and returned to the downstream heater core nozzle. The hose size is 1/4". I went to an industrial hose supplier, telling them that Gates makes 1/4" sized heater hose; they said they don't have that product. I said, what else is rated for say 240°F, 20psi, water-ethylene glycol mix. They sold me fuel hose.
