Abstract: Embodiments of seal device prevent migration of vapor into compartments that house electronics in a fuel dispensing unit. These embodiments deploy about conduits in a vapor barrier to seal gaps between the conduit and opening in plates of the vapor barrier and/or other components that separate the electronics from fuel-handing components. In one or more embodiments, the sealing device forms a radial seal about the conduit and a planar seal with the vapor barrier, where the sealing device is configured to maintain the planar seal and to allow relative movement of the conduit with respect to the vapor barrier in the opening. This relative movement can occur as a result of connection of the conduit to the fuel-handling components, e.g., a motor that can change position due to operation and/or natural settling of the support structure that supports the motor in the dispensing unit.

Abstract: Embodiments of a heating system maintains the temperature of a fuel additive (e.g., AUS32) at and/or above freezing temperature to avoid crystallization. The heating system can form a fluid circuit with one or more coaxially arranged sleeves disposed about hoses that transport the additives. The fluid circuit can also include a central compartment that encloses a flow meter. A fluid heater couples with the fluid circuit to provide heating fluid, e.g., to the central compartment. The heating fluid disperses throughout the heating compartment and into the sleeves, thereby direction heating fluid in thermal proximity to the hoses and other components that handle the fuel additive.
