Unboxed and used on a car, with some likes and dislikes. Bought on Amazon to check for Intake and Exhaust system leaks. The unboxing is kinda boring, however it shows exactly what you get. Zip ahead to 4:48 to see the unit in use.
It worked really well checking for Exhaust leaks through the tailpipe. I removed an Upstream O2 sensor to make sure smoke was getting up that far. The pressure generated actually filled the exhaust system and spit the bung/adapter out of the tail pipe.
I would be reluctant to check an Evap system with this machine because of the pressure.
