Do not mount directly on engine, intake/tubing, supercharger, etc. All pumps will run during prime and during engine start. Ensure pump load/battery/starter/charging system are adequate. Engine must pull more than 12inHg vacuum during idle and cruise, otherwise secondary pumps will run continuously. Consider the Honeywell Pressure Switch if the engine pulls inadequate vacuum.
