I think though, that to have a true continuously pressurized system all the way out to the nozzle, you can't get that just by changing the pump. There has to also be a valve out at the nozzle. Coolingmist has another new part that I think is probably for that purpose. It is a beautiful stainless solenoid operated valve for 50 bucks.
They kinda dance around the progressive pump thing. Sounds like pressure in the pump will always be high, but pressure in the line (and at the nozzle) I doubt it, there's still no on/off valve near the injection point. They must almost have a solenoid on the actual pump that they can progressively open with their controller.

Not yet unfortunately. After the BBX and MAP downpipe I am out of mod $$ for a while. Tuning the car at DB Performance tomorrow for pump gas, I'll rock it like that for a while, not sure where I'll go next. I'd *LOVE* to put one in though as the trunk has the perfect spot for a nice big tank once a mini battery is in.

its a small spring loaded unit that pressurises under pump pressure and then keeps the line pressurised when the pump turns off...

806-409 is purely mechanical.
but yes you need a solenoid/valve at the jet end otherwise the pressure would be released immediately
the Aquamist kit has a FCM (Flow Control Module) which is an electronic solenoid able to be pulsed at different duty cycles to allow for different rates of flow. So when its closed the pump keeps the line primed, and when the pump is off the 806-409 part keeps the line primed.
That way the Aquamist is "instant on"
