I have the SSBC Vacuum pump to give my car brakes, since I have none with the vacuum my enigine now produces. The other day the vacuum switch that turns the pump on when no vacuum is present (and off when a certain level of vacuum is reached)went out. I called SSBC and got a new one under warranty, and ordered another one just in case, for 12 friggin bucks. They claim that I cant find this switch anywhere in stores. Do any of you guys know of a switch that could be used in its place, something that I could pick up at AutoZone or O'Riellys? I think the switch turns the pump on when it detects less than 15" Hg, and turns off when 22" Hg is detected.

 

goto a houshold/commercial HVAC supply store.. should be around $4 and be completely adjustible.
