I had problem with land rover 130 fuel cap after replacing it cause I drove over one fitted, must of tried 3. 

Then went to land rover garage I use for spares and they gave me a original one and that never leaks, they said its the breather setup in patterned ones. 

 

I tried the other year to get hold of a proper cap off predator. They sent me the wrong one which was for newer machine. And then it was a case of computer says no and told me my machine was too old lol 😂
