Abstract
A quick connect fitting for coupling a first component of an evaporative emissions system of a vehicle to a second component of the evaporative emissions system is provided. In one example, the quick connect fitting includes an indicator section that includes a color-changing material that changes color based on an extent of deformation of the color-changing material, where secure coupling of the first component to the second component is dependent on the extent of deformation. In this way, it may be readily determined as to whether a particular quick connect fitting is securely connected, which may improve engine operation, reduce undesired emissions, and reduce warranty rates.
