A fuel filler door actuator including a motor, a gear train coupled to the motor and to a latch arm, and a locking cam coupled to the gear train. The locking cam resists movement of the latch arm from an unlocked condition to a locked condition. A manual override cable is disclosed for manually moving the latch arm from the locked condition to an unlocked condition. A push—push mechanism is disclosed for allowing facile opening of a fuel filler door, and a quick connect/disconnect feature is disclosed for allowing facile assembly of the actuator to a fuel filler door housing.

The HVAC duct coupling of claim 7 wherein the gasket includes opposed ends and wherein when in the expanded configuration one end of the wedge-shaped gasket assumes a concaved shape.9. The HVAC duct coupling of claim 7 wherein the bead formed on the duct coupling abuts the end of the HVAC duct when the duct is connected to the duct coupling.10. The HVAC duct coupling of claim 8 wherein when in the expanded configuration the concave shaped end assumes a height greater than the height of the other end such that the outer surface of the gasket generally slopes downwardly from the concaved shaped end to the other end.11. The HVAC duct coupling of claim 7 wherein when in the compressed configuration the thickness of the gasket lying between the duct coupling and the duct is generally constant along the length of the inner surface.12. The HVAC duct coupling of claim 7 wherein the indention includes a pair of spaced apart edges and wherein when the gasket assumes the compressed configuration, the gasket is confined to an area that lies between the two edges.13. An HVAC coupling assembly comprising: a. a first conduit; b. a second conduit; c. a gasket for fitting around the first conduit and forming a seal when the second conduit is joined with the first conduit; d. the gasket normally assuming an expanded configuration and in the expanded configuration the gasket assumes a wedge-shape and includes an inner surface and an outer sloped surface that projects past the inner surface and forms an open area below a portion of the outer surface; e. wherein when the first and second conduits are joined together, the first and second conduits cooperate to compress the gasket between the conduits and cause the gasket to assume a compressed configuration between the two conduits such that a seal is formed by the compressed gasket; and f. wherein in the compressed configuration substantially the entirety of the gasket is compressed by the first and second conduits. 14. The HVAC coupling assembly of claim 13 wherein the gasket includes opposed ends, and when compressed between the first and second conduits, the thickness of the compressed gasket is generally equal throughout a substantial portion of the distance between the opposed ends.15. The HVAC coupling assembly of claim 12 wherein in the expanded configuration the gasket includes opposed end portions with one end portion being elevated with respect to the other and wherein the elevated end portion includes a generally concave surface that extends around the gasket.
