After closing my fuel tank windows due to leaks (at Hobbs 170 /3 years flying) I missed the precision of the content they were offering. Indeed the Moeller gauge is too inacurate and not linear from empty to full. Worse, in case of failure of the Moeller as we have already seen happening, you have no way to know where you stand above the max of the in-tank sensor.
Like the Fuel Tank Windows, this rod made of 1/8 inch fiberglass will not lie. It slides easily in the fuel tank neck passed the return fuel line. Just calibrate it from an empty tank and print the calibration on a piece of measuring tape as seen on the picture:
