My vacuum test seems good. Should they stop so easily?
I might replace my fuel pump with a dual stage to increase vacuum to the wipers.
Can I also use the dual pump to halp with vacuum brake assist?

I rebuit mine and it seems to work but not really any better. I have removed it once again to try to reseal it...I think it has a vac leak.

Cleaning and lubricating a vacuum wiper motor might help but most often it needs to be rebuilt (parts that wear need to be replaced). A dual-action pump should help but I have had bad luck after receiving a few dual-action pumps that had dried-out on the shelf or had been poorly rebuilt (I'll send them to be rebuilt by Fickens before buying another new or "rebuilt/remanufactured/reconditioned" one). | | | | | Joined: Sep 2005 Posts: 1,028 'Bolter | | 'Bolter Joined: Sep 2005 Posts: 1,028 | I was able to rebuild this again and it seems to work acceptably.
Thanks for the tips guys...I always learn so much on this site.
