Most still have the vacuum wipers and in most cases, they work about the same -- as well or as poorly -- as they did before. It is only on open throttle or load when they will suffer without the extra from the pump. Some with the PI fix have gone to a dual action fuel pump to supply the extra and one other poster has installed an Isuzu diesel type alternator with combined vacuum pump.

Not sure how big an issue since a lot of the washers may not work anyway but--- If you want to keep the original windshield washer action with co-ordinator present, I don't believe Craig's electric setup has the capability since it doesn't use the Packard cable actuated wiper switch. Maybe something could be figured out for the co-ordinator to mount and work an extra electric switch but that would be a project. If you can find the mid 50s Chevy electric motor, the co-ordinator will fit right on those and work. Otherwise, to keep the washer feature you will need to keep the vacuum motor.
