Claim 19:
20. A method of operating a heated hose assembly, the method comprising:
providing a first heated hose configured to transfer a first fluid component, the first heated hose comprising a first electrical connector and a second electrical connector each electrically coupled to heating elements of the first heated hose;
providing a second heated hose configured to transfer a second fluid component, the second heated hose comprising a third electrical connector and a fourth electrical connector each electrically coupled to heating elements of the second heated hose;
electrically coupling the first electrical connector to the second electrical connector such that a first key of the first electrical connector mates with a second key of the second electrical connector;
electrically coupling the third electrical connector to the fourth electrical connector such that a third key of the third electrical connector mates with a fourth key of the fourth electrical connector;
supplying a first electric current through the first electrical connector and the second electrical connector to increase a temperature of the first fluid component transferring through the first heated hose; and
supplying a second electric current through the third electrical connector and the fourth electrical connector to increase a temperature of the second fluid component transferring through the second heated hose.
