If it is a small rubber hose it would be for the vacuum booster to help the windshield wipers. These cars had a combination fuel & vacuum pimp with the vacuum section used to assist the wipers when manifold vacuum was low. The vacuum pump is in the upper part of the fuel pump and connects to a steel line that runs along the side of the engine block towards the rear and then by a rubber hose up to the wiper motor on the firewall.
