I attached the image of measurements I made with my "G" and its long-range tanks. I'm using the J-Hawk J-Air Fuelhawk 11" Universal AvGas Pre-Flight Fuel Dipstick. Also, I sincerely recommend a Fuel Stop - FuelHawk Saver attached to the fuel dipstick. It would be easy to lose the dipstick in any 337 fuel tank.
This was very time consuming work. Each reading was taken with the dipstick resting in the lateral channel that runs down the length of the wing tank. The lowest reading was made with fuel in that channel, directly below the port.
Use the chart at your own risk. Honestly, I will check the accuracy of my recorded data the next time I have the fuel below the filler ports.
The right gauge has stopped working since I bought the airplane. If the problem is in the indicator, I will install the Aerospace Logic FL212 electronic gauge on my aircraft; it is STC'd for the 337.
