well, I have yet to try it out, but I did get an adjustable vacuum switch, cycles the pump on at 18 inches of vacuum, just haven't had time to test it out on the truck yet. I made a Vacuum accumulator out of a 5 pound oxygen bottle, couple that with all the braided hose I should have quite a good vacuum supply.....
