ITP would this be a check it's working

I changed my ITP last week (and UPB today). I have driven about knowing the ITP was duff from the day I bought the car exactly a year ago. I have always driven with at least 1/4 tank, but now that the ITP has finally been changed, presumably I can now run it down to near empty (should I want).

The ITP is very quiet and if I open the filler cap I can just hear it. My head tells me just because I can hear it, it doesn't mean it's working. I wondered if I disconnected the UBP electrically and removed the tube from the UBP into the filter (and put the end into a bottle obviously), would the ITP on its own pump through to this point i.e. would I have flow?

I'd feel must better if I could prove it's actually pumping.
