When operating the EVAP-approved smoke machine, is it necessary to constantly control the pressure, or perform any other cumbersome tasks?
NO! The big-3 OEM’s requirement was very clear and specific; do not make the machine’s pressure adjustable! The OEM required a fully automatic machine that made it impossible for the technician in the field to make an honest mistake, by applying too much pressure into the volatile EVAP system. Besides, using higher pressure does not find more leaks – except maybe for the ones you’ve created. See question # 9 below.
