Re: 50 Clipper Project - Fuel pump issue help needed

Believe that is the part of the pump that provides an aux vacuum supply for the windshield wiper motor and would not directly affect fuel delivery unless the connection between the intake manifold port and pump is open. Then it would result in a large vacuum leak and lean mixture.
On a 50 model I believe the routing is still a steel tube from a port at the front of the intake manifold to the outlet side of the upper vacuum portion of the fuel pump. There were no 50 Clippers so if it is a 51-2 200 model which some mistakenly call Clippers I believe they had already changed to a port near the carb by then. If nothing is found in the location shown in the parts manual photo of a 48-50 engine check for a port on the side of the vertical portion of the intake manifold near the carburetor base.
To complete the vacuum routing, from the inlet side of the pump another steel line goes along the side of the block and bends up toward the windshield wiper motor area where it transitions into a hose going to the motor. The metal section from the pump to the wiper motor may be a single tube ending near the motor or two shorter tubes joined by a hose lower down at the firewall to lower bellhousing area of the engine
Here are a couple of illustrations on the 50 vacuum line. If you do not have the optional vacuum radio antenna disregard the tee and hose portion after the tee. The hose would just be a short length between the tube and wiper motor inlet.
