1. An adapter, comprising:
- a body including a first end shaped to couple with a diesel exhaust fluid (DEF) refill passage and a second end including an aperture shaped to receive a DEF nozzle;
a pivotable door sealing the aperture and forming an external surface of the adapter; and
a magnetic ring positioned within the body, downstream of the pivotable door between the first end and the second end, wherein the second end forms a nozzle insertion passage extending in a direction away from the pivotable door and the first end, with the nozzle insertion passage in fluidic communication with atmosphere, and wherein the nozzle insertion passage has a passage diameter less than 23.8 millimeters and a passage length greater than a length from a nozzle opening of a fuel additive bottle to a shoulder of the fuel additive bottle.

Abstract
Methods and systems are provided for an adapter for a fluid refilling system. In one example, an adapter configured for use with a diesel exhaust fluid (DEF) system may include a first end configured to couple with a DEF refill passage, a second end including an aperture shaped to receive a DEF nozzle, a pivotable door closing the aperture and biased against the aperture by a biasing member, and a magnetic ring positioned within the adapter and downstream of the pivotable door. The pivotable door may be formed of a material permeable to DEF vapors and may include a plurality of vent holes configured to flow vapors from the DEF system to atmosphere.
