I always carry a small container of gas line antifreeze in the trunk in case the gas line freezes. I have not had a gas line freeze for years but it is a pita if it happens if u don't have gas line antifreeze. Cheap insurance
The colder it is the more chance of condensation especially if you don't fill up your gas tank regularly. Not sure what P manual says about gas line antifreeze but in an emergency I would use it.
