Will,
Generally the larger of the two lines is the supply line and the smaller is the return line... This has been my experience.

The smaller line should be a vent line (for a Quadrajet, must be a 69+).
Just plug it and go on with life.

hey guys,
i just heard that if you plug your vent line and your gas cap isnt vented that you could run into problems with vapor lock. i was advised to just connect it to my vaccume can. and forget about it.
