Using a pressure measurement instrument to measure fuel level is very common, however most are scaled in bar or psi pressure ranges, and if they do happen to be scaled in level units, they are typically water level based, such as mH2O or ftH2O.
There are many different grades of liquid fuels which vary in density, plus changes in tank temperature will affect the density of one fuel type. So it is important to carefully consider the pressure range required to ensure that the level being measured never exceeds the operating range of the measurement device.

The conditions which will produce the maximum hydrostatic pressure, are the lowest tank temperature and the maximum tank level. If you know the density of the fuel at the lowest tank temperature and the maximum possible fuel height in the tank, then you can calculate the pressure range needed to ensure the instrument will never go over-range.
For an example, let’s say you have a Kerosene fuel tank that is 1,385 mm deep, with a maximum specific gravity of 0.82 corresponding to the lowest tank temperature of 15.6 degC. If you convert this to a hydrostatic pressure, it will come out as 0.1114 bar, 1135.7 mmH2O or 3.726 ftH2O pressure.
