A connector assembly includes a base plate that defines a fill opening and an aperture. A fill tube is coupled to a first side of the base plate. The fill tube is aligned with the fill opening. A radial flange is coupled to a second side of the base plate. The radial flange extends around the fill opening. A toggle magnet is coupled to the first side of the base plate proximate to the aperture. The toggle magnet is operable between an activated state and a deactivated state.
