Review on OURANTOOLS Automotive EVAP Machine Leak Detector: Efficient DC12V Auto Fuel Pipe Leak Tester for Cars, Motorcycles, and Trucks by Jeff Pettis

This thing worked great for me, helped me find leaks on 6 different cars in 5 minutes, super easy to use, the only part that was a little unclear was the clear bottle The one that comes with comes with a label saying you need to put in 20-30ml the first time. I assumed each line on the bottle was 10ml which was wrong because there was no clear marking, the bottle at the top is about 30ml.
