The fuel pump was a dual purpose pump. It had a vacuum chamber on the top of it to operated the wipers. A hard line came off the top of the fuel pump and ran below the right valve cover. Then converted to a soft line at the fire wall and to the wiper motor. Without the fuel pump you will have to run the vacuum from the carb. If you have power brakes then the carb will have to supply vacuum for the brakes and wipers. Depending on your RPMs this can cause performance problems for both brakes and wipers when used at the same time. I don't remember the name of the company but there is a website that offers a electric wiper motor for 50s Olds. Just a thought. Take care.
