I suggest putting a system bleed down, return to tank valve when the engine is switched off.

That?s why I got a third solenoid but it is still risky? If so I need 2-way solenoid just after the accumulator and another solenoid towards the tank otherwise it will empty whole accumulator.

No reason, this pump came with the set, I never thought about that. I was thinking that the accumulator would make sure for a steady pressure.
I found the way to make a digital flow gauge for cheap, I don?t know how long it will last but I am going to try it to see what happens.
This is the in car panel I am going to make, it is not totally at scale since I decided to get another display. The temperature thing is just a bonus, it can read 4 temperatures (PT100), flow meter reads actually RPM but there is a calculation to see how much water goes through:
