hi everyone,
This is about improving the wiper motor performance without converting to electrical.
My wiper motor has been rebuilt professionally. Works great when it has enough vacuum. My fuel pump develops about 10 inches of vacuum which results in marginal performance. I could replace the pump but no guarantees another would be better or that it would stay that way (don't use the wipers all that often). I did have a pump which developed near 20 inches for awhile and the wipers worked awesome but the pump died on the gasoline side of things.
So...following the power assisted brake guys, the idea came up to have a tank in between the pump and the wiper motor. The tank would have two check valves in it so as to retain a pressure differential (vacuum) which would result in smoother and better wiper action.
Sounds ok on paper. Has anyone done or seen such a set up? Questions would be a) what did they use for check valves? b) how big a tank? c) how much better did it work?
thanks!
John
ps I have to admit to being partially motivated by the fact it has rained more than 50% of the summer in the Northeast US...
