[Tigers] FIller neck vent question

[Jim McLaughlin]

Good Morning all:

I am putting my car together and it runs, wow.  The fuel cap filler neck has
a vent that points towards the front of the car.  My question is what does
this connect to or is it open, which doesn't make any sense.  I cannot find
any details in the either the parts books or either service manual, (Alpine
or Tiger). Any help would be appreciated.
