A method of forming a grounded electrical circuit in a heated hose is provided. In one embodiment, the method includes: positioning a ground wire, a first heating wire, and a second heating wire axially within an inner wall of the hose removing the end portions of the heated hose, such that end portions of the first heating wire, the second heating wire, and the ground wire are exposed and positioning a ring around the first end portion of the hose. Exposed end portions of the first and second heating wires are folded to be positioned axially along an outer surface of the hose body. The exposed end portion of the grounding wire is folded radially inward, such that the grounding wire is positioned axially along an inner surface of the inner wall and against the ring. A stem of a first fluid coupling is inserted into the first end portion of the heated hose, such that the stem contacts the exposed end portion of the grounding wire.
