Connect everything exactly as it is pictured in the video. You'll need to loop the nylon tape around the threads (once is sufficient, twice if you really want to) before you screw on the female connectors to make the seals air tight. I'd recommend testing your pressure tank with nothing in it, make sure it holds pressure for a few hours before you use it. This also gives you dry run practice for when you need to quickly seal the unit before the resin starts curing.

MOST IMPORTANT:
Be safe. Do not skip any steps while you quickly hook up the pressure tank. It's better to ruin $2 worth of resin vs making a dangerous mistake.
