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.

1. A method of forming a grounded electrical circuit in a heated hose, the heated hose comprising an inner wall, an outer wall, a first end portion, and a second end portion, the method comprising: positioning a ground wire, a first heating wire, and a second heating wire axially along the heated hose and within the inner wall;removing the first end portion and the second end portion of the heated hose, such that end portions of the first heating wire, the second heating wire, and the ground wire are exposed;positioning a ring around the first end portion of the hose;folding, at the first end portion of the hose, the exposed end portions of the first heating wire and the second heating wire radially outward, such that the exposed end portions are positioned axially along an outer surface of the hose body;folding, at the first end portion of the hose, the exposed end portion of the grounding wire radially inward, such that the exposed end portion of the grounding wire is positioned axially along an inner surface of the inner wall and against the ring; andinserting a stem of a first fluid coupling into the first end portion of the heated hose, such that the stem contacts the exposed end portion of the grounding wire. 2. The method of claim 1, further comprising removing a length of insulation along each wire in order to expose the wire. 3. The method of claim 1, further comprising attaching a thermostat to the exposed end portions of the first and the second heating wires at the first end portion of the heated hose. 4. The method of claim 3, further comprising: positioning a ring around the second end portion of the hose;folding, at the second end portion of the hose, the exposed end portions of the first heating wire and the second heating wire radially outward, such that the exposed end portions are positioned axially along an outer surface of the hose body;folding, at the second end portion of the hose, the exposed end portion of the grounding wire radially inward, such that the exposed end portion of the grounding wire is positioned axially along an inner surface of the inner wall and against the ring; andinserting a stem of a second fluid coupling into the second end portion of the heated hose, such that the stem contacts the exposed end portion of the grounding wire. 5. The method of claim 4, further comprising attaching a power cord to the exposed end portions of the first heating wire, the second heating wire, and the ground wire at the second end portion of the heated hose. 6. The method of claim 5, further comprising inserting an expansion tool into the first fluid coupling and the second fluid coupling to radially-outwardly expand each stem against the inner wall of the hose and contact the exposed end portion of the grounding wire. 7. The method of claim 1, further comprising positioning a protective sheath over each end portion of the hose to protect the exposed end portions of the first heating wire, the second heating wire, and the grounding wire.
