Does your gas door flop open or not stay closed properly? Don't replace the whole housing – it's probably just this little spring that's broken. This is a direct replacement gas filler door spring for certain Ford/Lincoln/Mercury models like the Fusion, MKZ, and Milan from around 2010-2014 (double-check your exact model and year).
It's a simple metal spring that provides the tension to keep the fuel door securely closed. Over time, these can wear out or break. Replacing it is usually a quick fix – you might need a small tool to pop the old one out and clip the new one in. It restores that satisfying 'click' when you close the door and prevents it from rattling open while driving. An inexpensive, easy repair that solves an annoying problem.
