Yes - the NBR tube in the fuel line will work with ethylene glycol, BUT probably won't hold up as well due to temperature. Generally the fuel line is rated to 200 deg F, while EPDM heater hose is rated to 300 deg f.

5/16" dia EPDM heater hose is hard to find, but is available - the Goodyear p/n for it is 65027 or 65015
