I use sight gauges for all three = tanks.
 
The top of the gauge is connected to a T at = the wing=20 tank tip vent with a tube, called the reference leg, to provide proper = pressure to balance the fuel column.
 
During testing I accidentally ran a tank dry = due to=20 condensation in the reference leg causing a pressure differential that = resulted in a high reading. I solved that by collecting pitot air = pressure=20 with a tube on the belly and metering it with an orifice through the = reference=20 legs keeping them clear of condensation. It has been trouble free = since then,=20 2000 hr.
 
I always keep plenty of fuel in the=20 header.
 
If there is serious interest I will take some = photos=20 and draw a sketch.
