The the outer cover cap that matches your trucks paint doesn't stay closed anymore. One day after filling up I closed it and noticed it didn't snap into place, it's like there is no mechanism to hold it in. Now it stays open a little bit. Is this easy to fix/replace?? 04 model.

Pretty common problem it happened to me about a month ago

 

Thank you. I was hoping it wouldn't be difficult.

 

Wow, thanks! Now I've gotta order one for my flareside!
