2. Install a fuel totalizer.

This tells you how much fuel you've used, not how much fuel you have
left. It's the fuel you have left that's important. Granted a
subtraction will get you there, but that depends on the very assumptions
that will bite you one day.


My RMI engine monitor gives fuel remaining PLUS fuel endurance (time)
based upon current consumption rate. Add knowing time to destination
plus reasonably accurate fuel gauges and I am set.

I know my gauges are good at the bottom end (where it really matters)
and the fuel remaining is good because I have run tanks dry
deliberately to verify useable fuel. No guessing.
