Not to vieuw from the Netherlands..safecraft website said:Access from your area has been temporarily limited for security reasons
Hi Howard,I found these:
Great smart home option for automatic shut off of potable water. This motorized ball valve will allow full flow without restriction, something that solenoid valves lack. Once power is cut/lost, the power from the charged capacitor will proceed to close the valve. Unlike standard solenoid valves...www.electricsolenoidvalves.com
I sent them a email and asked if they could be configured to normally open so that if power was lost then it would dump any fluid pressure and if they were comparable with gasoline.
Here was their response: I think this would work with a separate return line to the fuel tank.
You can absolutely configure this to be normally open however these ball valves consume such a negligible amount of power to remain open that it is usually unnecessary. For example many people use these on their vacation homes and have them powered open for months at a time while they are there.
Here are the steps:
1. notate the position that the actuator is in upon opening the box for the valve
2. remove actuator
3. under the actuator is a coin size disc that you can take a flat head screw driver and twist the ball manually to open.
4. put the actuator back on but at a 90 degree turn.
5. Test the valve.
We have had quite a number of customers successfully do this. One of our customers also created a document outlining these steps in more detail. I've attached a file outlining how to convert these.
These valves are compatible with fuel.

Ethanol & aluminium don't match either as the alloy corrodes very fast by ethonal. So be carefull with using alloy tubing as a hardline.I guess with the issues surrounding ethanol and fuel hose nowadays, there something to be said for running as much as possible in hard lines with just the connections in hose. Then following a regime of regular renewal of those connections..

What about the aluminium fuel tanks most of us are using? Should we be doing some sort of preparation before laying the car up for winter?
