Aux tank without vent?

[iwlbcnu]

replaced my aux tank, and see that the replacement doesn't have a vent tube hole? I have never seen one like it, but it does have a Ford logo on it. The sending unit also had a return line on it. Could this be from a pick p or something? The tank and skid plate all fit in the EB fine.

Yeah, the early Broncos used a vented gas cap therefor not needing a vented line to the tank.
