Joshua, I recommend using a product called LPS #1 Runs about $10 a can.?This is a far?better
greaseless lubricant for switches. Will also mix with the old grease and make everything work much better.

When I bought my car 4 years ago the vacuum pump ran all the time. I
thought that it was a pretty poor design until I was educated by the
Forum and Gordon.
I removed the pump and cleaned the switch as recommended by Gordon and
haven't done a thing to it since and it works fine. I believe that has
been the case with a number of owners.
The switch likely has a sticky lube from the manufacturer. WD-40 or a
similiar product seems to work better. WD is a great parts cleaner and
usually doesn't over lube.
It is also possible that you could have a vacuum leak so if you have
the gauges you could check for excessive bleed down. But most likely
it is the switch.
