the reed switch device is available.
<http://www.avnet.co.uk/lts/fuelgauge.php> Talk to Gerry Davis and tell

Tony K might sell you the chip and details for his gauge, ask him.

The first stand alone gauge of this type was installed by Graham Clarke
in the earl;y days. He used an old ASI to sense the head. Tricky to
engineer but it did work. Our PFA weren't happy but Graham was a skilled
innovator who worked for Marconi on radar and stuff.
