The hose / line that connects the liquid fitting on the condenser and the orfiice tube fitting on the evaporator. This is the hose that lays on top of the radiator/ fan support cover. It is often bent-up and damaged after radiator removal. PLEASE NOTE: There were several different versions of this hose made from 1981-1988. This hose is meant to replace all of those hoses and is not an exact reproduction.
