Q: I have a Broken fuel door latch and it doesn't look good 

To repair the fuel door latch, open the trunk up and remove the side covering panel where the fuel door would be located at. There you will see the the fuel door latch with a harness on it. Remove the harness and go to the fuel door. Use a 10 mm socket and remove the bolts to the fuel door latch. It will come off into the trunk. Install the new fuel door latch and secure the bolts with additional help. If there is no help, you can use tape to hold the latch in place so you can start the bolts. Then remove the tape and tighten up the bolts. Then hook up the harness and put the cover panel back on. Now you can test the fuel door latch and see if it works.
