This is not the actual actual gas cap to the tank. Instead its the cover that you open to reach the cap. The little white thing seems to go in and out of a mechanism. Cant tell what it is for but mine is now broken off. The cap still works, shuts, stays shut no problem.

Should I be concerned? What is it? Get it fixed? Sorry no pix.
