When connect to 12v power does the pump come on automatically, even when the switch is in the off position?

This AUTOOL SDT202 in the power on the air pump began to work, the switch is used to control the smoke.

So I returned the one with no gauge and bought this one but I’m using mineral oil how to combat oil spit?

I used baby oil and had no problem

Can’t tell if that is a tailpipe adapter (cone shaped thing) that comes with this unit. Or is it too small to fit in the tailpipe?

This AUTOOL SDT202 smoke tester, the package list contains (cone) adapter,Made for larger openings with a diameter up to 3.26 inches (83mm) and as small as 1 inch (26mm).
