electric vacuum pump installation
hey guys, i recently purchased a electric vacuum pump off of ebay. It is meant for an ambulance, but for $150 i am going to make my own kit work on my truck. I have a relay, and the neccessary wiring to complete the job. One of my questions is plumbing the vacuum hose into the brake booster, does the vacuum pump plumb directly into the booster itself, or can it go inline with the hose coming from the carb vacuum source? also my other question is the pressure switch or vacuum switch, which would be better to use, or can i even run a pressure switch on this application.
