Charley,
Did you sump the tank prior to refilling it to ensure that it was truly
empty?  You may be looking at 3 gallons un-usable.  The Legacy wings have
little dihedral and there is a lot of sloshing.  You may have unported the
fuel outlet finger strainer and made you think the tank was empty.

When I calibrated the fuel gage on my Legacy with speed brake wells, both
tanks were 36 gallons filled to the bottom of the fuel inlet.  37 gallons
makes sense if you don't have the speed brake wells.

Subject: [LML] Fuel vol correction

I may have provided some bad info in the past.  I stated that the fuel vol
in my wing tanks was 37 gal per side; attributing the extra to the complete
absence of speed brake provisions.  However, I just got around to exhausting
a fuel tank in flight, and refilled it with 34 gallons.  Of the many
possible variables, the one that seems most dubious is the accuracy of the
1/2 gallon measuring cup that was the basis for the original calibration.
I"m still sorting through this one.
