I noticed below someone indicated fumes and vacuum as a possibility. I notice when and if I fill my tank almost to the top it is extremely hard to almost impossible to close but if I do not almost over fill my tank I have zero issues. I also sprayed a little silicon spray too.
If you fill to the top you can overfill into the evaporative cannister. I let the pump kick off once and then I stop. Then the fuel level is 4-6 inches below the cap. I easily get more than 225 miles on a tank so (IMO) there is no need to squeeze in that last bit.
YMMV
