aquamist HFS2 FAV problem
 

I have got aquamist HFS-2 kit and problem with FAV (fast active valve). Nozzle stopped working cause FAV failure only after 4000km from installation of kit.
I used only water or water with metanol 50:50
Coil inside of FAV is clicking while connect its pin to 12v source, but not working (nozzle is not squirting). I also measured pins between each other with ohmeter - result is 11,8 ohms.

When I connect nozzle directly after high pressure pump, it is squirting well. Is it necessary to connect FAV inline, what is its function for?

Should FAV be normally (without power 12V source) open or closed fast acting valve? Is it possible to exchange it with something like this?

No response here?, seems to everybody uses intercoolers :) I know that intercooler is better option, but in my setup it is no space to use it.

I just order "chinese" (but what is not pruducted in china these times?) solenoid valve and installed it instead aquamist "FAV" solenoid valve. Output from it connected to hose with injector fixed to wiper for tested it by car running. It started to squirt water about 4000rpm and ammont of water raises dependence of boost/rpm.

I paid 10,-usd for that solenoid valve instead of 100,-usd for aquamist "FAV" crap.
