Hi,

  Attached is my idea of a simple fuel system for my Vision low wing
  aircraft.
  Will this work or am I overlooking something?

  Regards,

  Not a bad idea. Looks like it is worth a try. Monitor the tank
  quantities when testing to see what happens. I assume there is a
bit  of dihedral in the wings.

  Pierre,

What would happen if someone closed the shut-off valve while the
pumps were running?

Mark S.

Good point Mark. Probably best to forget the valve and turn off the pumps.

You could use Swagelok check valves with a 1/3 pound cracking pressure as the
non-return valves. That way when you shut off one pump and start the other the
fuel goes to the engine and not to the first tank.
