It's a device for emission gasses. They had various devices that would collect the vapors and recirculate it back into the engine to be burnt again in a second combustion cycle. They hoped that this would help with emissions. Didn't do diddley! Actually, it only helped the mechanics of the day, as it would cause the engines to need tuning more often. YANK IT!
