2nd Gen LS400 Refuel Problem

HELP: I just got my new (to me) 2000 LS400 and she doesn't want to take gas. I have to pump it unbelievably slow or it starts backing up the neck. I've been told it could be that a fuel vent is blocked. Any thoughts..... and where do I check to see if it's blocked ???

Thanks.
