Come on guys, keep it civil.
Otto's earlier message to indicate that is it not an exclusively Ford complaint becaise everyone who used that system had similar issues.
Both are true statements. Anyone with a vacuum wiper system will have issue (see any number of previous discussions around here for examples). That includes both Fords and Chevrolets.
@Panic: there have been a couple discussions of adding electric vacuum pumps and/tanks to help with that. I want to say that Coilover had a recommended vacuum pump from a diesel that he recommended. I found one for sale on amazon that I had linked as an option, but a couple members posted that they had tried that style and it did not have enough volume to be effective.
