Went to close my fuel flap to find that I will no longer latch shut. It appears the little latch on flap is not hooking onto the little flap release part. It's like something has come off the little release part bit as the actual flap itself appears to be fine and nothing broken. When I look closely as i try to shut the flap, it's like the release bit attached on the left side just don't hold the flap latch? So now I'm having to push and fiddle with the flap so it holds shut but coz its not latching shut it pops open and of course at night some dim witts are trying to bust open the petrol cap (I have a locking fuel cap with key) and steal the fuel or tamper with the fuel. Anyone else had this happen to them? How to fix? What's the little black bit on inside left of actual fuel opening that holds the flap locked shut called(fuel release bit???).
