06 GV fuel door latch
 

The Fuel door latch on daughter's GV has broken, and the fuel door wont latch shut. I've searched in the Factory service manual (JB627), and everywhere online, and I cant find anything on how to fix this. There is a black, round plastic part that mounts in the body that seems to be the latch and seems to be broken (see picture). Does anyone have any ideas for a fix, or where I can find this part?
Thanks in advance,
