Pressure pumps?

LOL ok I thought I fixed all your problems. But i'd still be curious to know what the airflow is like just from the pump itself. I think the pump will put out the same amount no matter what so the two things aren't necessarily working together.

Pressure is not a good thing from your piping. Smaller diameter pipe adds pressure to the pump head meaning less flow. The more flow you put through that Beckett thingy the higher velocity though the restriction will be meaning a higher outwards pressure drop at the airline ultimately meaning more air will get sucked in. You don't want to restrict your flow before you even get it to the Beckett. Its really all about velocity through the Beckett, pressure rated pumps will do that better but decreasing pipe size prior to increase head pressure makes zero sense.
