does anyone make, or know where to get a hobb switch that turns on at 4in of vacuum and lower? i need it for a dual pump fuel system to activate a second pump before boost is created so the fuel will be at the rail when i start to make boost, thanks, Andy

Try and find a catalog. I'm sure they make adjustable ones

they make adjustable, but they are designed to turn on and off at a given differntiation, like if it is set to turn on at one and the differntiation is 2, then it will turn back off at 3
