I have aux wing tanks in my airplane that do not have fuel level senders installed in either tank. These aux tanks feed my main tank, and my engine is fed strictly from the main tank. I have my D120 setup to show my main tank fuel level, fuel burn, etc. I would like to do the following in my D120: I want to manually input the total amount of fuel in my aux tanks which will display on my D120 aux tank indicator. Then, when I pump the fuel from the aux tank, I want to go into the D120 and manually adjust the amount of fuel remaining the the aux tank. Is that possible to do?
