Donald. While measurements of Gallons are a good thing to do for your weight and Balances calculations, what you really want to know is how long you can fly on a certain amount of fuel left. For that I would check the time between the bobbers in the wing tanks stopped "bobbing" and the moment the header tank wire starts sinking while flying. In my plane this are around 20 minutes. Although I am having the round fuel gauge inside the tank, the cork swims somewhat outward of the tank root and hits the base early. The header tank is easily drained on the ground. You can drain it down to where the wire hits the cap and measure what is left of it. In a canister. But the plane sitting on the ground is not the same level as the plane flying in the air. That's why all values are just approximate values. One can make estimates with it, but can not rely on it.

Due to the dihedral approximately 2 gallons are still useable when they show empty. I know I can fly quite a bit yet until the header tank starts going down. --- In [email protected], "hogowner82" <hogowne...@...> wrote: > > Has anyone measured the drop in the header tank fuel gauge stick versus > gallons?
