"Sight" Fuel Gauges

[Area 51%]

Yup- so did I.

However, 3 years of operation with this setup has left me with the distinct feeling that this is a slight climb mode (positive aoa) for the airfoil, causing a higher fuel level in the sight gauge than strictly available. As yet, I have not decided if this is an issue that should be dealt with.

Simply take your digital level up with you and check the angle when you're in stable flight. Adjust the plane to that angle on the ground and re-calibrate the tube.
