Good luck with this, Bill.

The non-return valve will ensure that the main pressure switch will not know what the pressure in the 300 L tank is.

The only way I can see it happening is if you put a pressure switch between the non-return valve and the tank, with a signal back to the throttle.

You can get pressure switches that work on, and signal, with air only.

I cannot tell from the photo what this valve is.

Anyone else?

Cheers,

Bill
