Thank you wise ones for your replies but I just looked under the dash and was surprised to see two vacuum lines hooked to the wiper motor. Should I disconnect one of them? one goes from the intake manifold directly to the wiper motor. The other one goes from the carb to the fuel pump then from the fuel pump to the wiper motor. The diagram that was forwarded only shows one line. Please let me know if this other line should be left alone or disconnected and plugged. Thanks
