Just so you know, there was no such thing as a GMC Sierra in '68. That trim package came along later.

The sender with two ports is for a 72 if I remember correctly that extra would go the the purge canister witch you don't have . BUT if you have the right gas cap for your year it is vented and then if that indeed is the case you can plug that port with a vac cap no problem. Jim
