Being a lifelong boater (100ton Captain) and a pilot (10,000 hrs plus, over
60 years) including over 4,000 hours in helicopters, Fuel is high up my
priority list. Owned GMC's since 1979, over 250,000 miles in them. And I
have always used the system in a GMC as the way I feel was intended- run the
main tank until it (almost) runs out, or does run out, switch to aux and
find a station with the approx 6 gallons you have left. Yes, take in
consideration the ups and downs of the road...bla blabla. I also know my mpg
and get fuel before I pass the 300 +- mile mark.
If you want to REALLY know, buy an instrument up to the task. I never owned
a personal helicopter that I didn't install a fuel flow gauge. Most of my
personal aircraft had them as well. They include a transducer in the fuel
line that tells you how much fuel you are using and more importantly, how
much fuel you have used. Then do the math. Fairly cheap (see fueltron for
example).

Dean, love that idea. Very important gage when no tires on the ground. When I run out of gas I come to a rolling stop, not so much I would imagine for anyone flying. A little bit more involved to get wheels safely on the ground. Great suggestion, I always thought it would be nice to apply a number on gallons of gas used and left in the tanks.
Thank you,

I love the idea of a fuel flow gauge - no guess works, fill the tank, reset the gauge and that's how much fuel you've burned.
Assuming a cheap one would be accurate.

The EBL system will display a calculated gallons of fuel used, but it is calculated, not measured. I'm guessing to measure it you would need to measure the fuel delivered by the pump, less the fuel returned to the tank.
But these are also '70s era fuel fill systems. So did you get 35 or 40 or 50 gallons in your tanks? I'm remembering the fill behind the rear licence plate. Usually got a fuel bath trying to get a full tank of gas.
