Without pics it's a bit of a guess, was there a datto with a smog pump as some manufacturers used or an air admittance valve as others used to let some fresh air into the exhaust and burn up the rest of the fuel? Ford used a system that was just a one way valve, a number of others used small air pumps. Circa early 80s
