I think your talking about the heat riser vacuum line on a stock air filter. The line runs from the carb to valve under the air filter and then from the valve to the baffle on the fresh air intake duct. Basically, this directs warm air from around the exhaust manifold into the carb to help a cold engine warm-up faster. Once warm, the baffle should open to allow cold air in.

probably you need to examine all of the hoses they may have been all hooked up wrong over the years...if the car started to run better what comes to mind is that something was restricting air flow....
