12 Volt vacuum pump problem

Is your system completely separated from the engine vacuum?
try connecting the pressure switch straight to the booster.

just read the question asked in post 6.

with lots of reservoirs it may reduce the frequency of pump starts but when it starts it will run longer to charge the booster and all the reservoirs.

Less frequent starts but longer run time. Same idea as adding a tank to an air compressor. More reserve but longer to recharge. I ran 1/4" line to charge a remote tank so my compressor wont run continous.
