Help N2 method problem

[Couldydays]

I just bought the same EEBD hood like vizzy's and a Nitrogen pressure regulator with flow meter.But how can I connect these two together？The parameters of the flowmeter output port are outer diameter 8 cm, thread M12×1.I used that eebd hood with out the passing the gas,and felt a little suffocated,is it normal？
@GasMonkey any advice？Need your help.

The Hood is quite tight

I imagine if the N2 is on it should push the air into the hood, rather than the force you're exerting to pull in air when it's off. But I don't have a set up, so I'm not sure, just pulling from what I know from reading about the method.
