My experience has been if you close off the small top vent lines - you'll
(occasionally) suffer having to "burp" your gas tank (even with an empty
tank on level ground), while filling it.

Of course this always happens while you're in a hurry, and no matter how
slow the fill rate.

The top vent lines run to a fuel/air separator. If your plastic fuel/air
separator is non-functional - in a previous thread, someone posted a photo
of a copper tube version which would probably out last the typical 345.

If you don't mind the other people present at the gas station wondering
why you're rocking your Scout (to burp it) - it's good exercise. . .
