How do you plug the vacuum side of the pump if using electric wipers ? Just run a loop from one side of pump to other ?
If you have a '55, you likely have the 2 bbl 2204s carburetor.
The best/cleanest thing to do is to remove the (vacuum) line that runs from the vacuum port on the throttle body, located just below the carburetor on the back (firewall) side, to the vacuum wiper assist on the fuel pump and then plug the (now open) port on the throttle body.
It's important that you plug the open port on the throttle body, otherwise you will have a significant vacuum leak and the motor will not run.
As for plugging as the vacuum assist ports on the fuel pump, you can just leave them open or, as you suggest - run a loop from one side to the other.
If you have the single barrel 2467 carter carb, use the same procedure outlined above - although the location of the vacuum port is, I believe, on the intake manifold.
Hope this helps,
