I am trimmed. I hold the cylinder tight and once it builds a bit of vacuum to stay on it does not build vacuum to pump. Even if I directly such on a different body part lets say the belly skin to see if it creates suction. It does but I cannot build enough to pull the skin just holds the cylinder in place.
The female connector was on the cylinder and ordered the male separately. They fit so I assume they are the correct size.
Why does the leluv page says only capable of -1 to -3 negative pressure. Here it is recommended to go to 5h. Not sure if it is a weak pump. But how could that be it is for professional brake bleeding kit.
What is only 1 inch of mercury?
I have to find out what is the problem. Whether I should get a cylinder without a quick release or return the pump and hopefully get a refund to get a different one.
