Question for Aquamist and water pressure selection

That would make sense the longer the hose after the HSV that a low cycle would never actually build up the correct pressure at the jet with a low IDC. I think you will find that the closer the hsv (with pre stored pressure behind it) is the jet it will atomize better at lower IDCs than if the hsv were further away.

It is not the HSV to jet distance. The HSV is mounted about only 4 inches away from the jet.
Then the 40cc accumulator is mounted 3-4 feet behind them and everything else (check valve, manifold, water pressure switch, pump) is feet away back in the trunk of the car right next to the battery.

The setup was same exact one during the low IDC test too.
So the HSV was right next to the jet with pre-stored pressure (accumulator too) - the pressure was whatever the 2D does at stock settings - currently I don't have a gauge to monitor it.

So back to the pressure now Do you think upping the 2D pressure switch setting to 100 psi will help? Or is any other value suggested? What is the max before things start breaking? And why was it set at 75 from the factory ( hey, Richard L ? )

What pressure gauge should I get? Does the Aquamist one which uses a 4mm line in a tee work fine? Do I have to take the air out of the line to the gauge, or just tap it in the tee and not to worry?
