the fuel pump is to get fuel to the carb. the other funtion is to boost the vacum to the wiper motor. so the ? is elec. wipers are the way to go. then the fuel pump is pumping fuel. I am no exprert but is has been my expriance vacum wipers suck. vac.ast. wipers suck.so fuel pumps pump fuel. elec.wiper motors power wipers. there is a reason modern cars have spearated the systems.it is 6 of one,or a half dozen of the other. if you get your vac. wipers to work good let me know. god know i've tried.I dont want to sound like a smart [censored] or know it all. but I converted mine and never looked back. so that is my humble thoughts on the matter.

theres a tool for every job,and that tool is a hammer. it's easy to give advice if it's not your pocket book at stake. A well thought out plan,Is nothing. Untill exacuted twice.
