There actually is a fairly inexpensive way to know how much fuel you have in
your tank . Know how much fuel you take out. I was the distributor for the
Enstrom helicopter in the West for a number of years and equipped most of
them with a fuel flow transducer that calculated the total used by the
engine. Pretty simple to figure when you knew how much you had put in.

Still available, just an inline device hooked to your 12 volt and a gauge.
Don't know current costs.

Dean (and anybody else interested)

Look up [URL="http://Floscan.com"]Floscan.com[/url][/url]. They are still out there, they are not as expensive as the dynomometer laboratory grade units, but they are also
smaller, lighter and easier to install. They can't be used on anything with a return flow for lots of reasons (we tried). Then again, in a GMC there
is little threat of falling out of the sky or being lost at sea.

I have often thought of that type of measurement system. Then I fallback to the time (stopwatch) or odometer based measurement system. Mine is
simple and it works though probably not as accurate and a transducer based system.

I have new SS senders, but the one in the Main isn't very accurate (my
custom calibration wasn't very good); and, I apparently shorted the one in
the Aux while re-installing the tank. Neither of them bothers me very much
because I have a more reliable fuel management technique:

Since my EFI return line goes to the Aux tank, I always know that its
reserve is there. So, I run on the Main tank until the engine sputters,
switch to the Aux, and look for a service station. With 6+ gallons
reserve, 8 mpg gives me about 50 miles to find fuel -- 'tho' I usually stop
long before then anyway.

If you have a GM throttle body EFI and the EBL system, you can add WinLog-EBL to get three resettable trip meters that display miles, gallons, and MPG
on a Windows screen. It uses the EFI pulse width info to calculate gallons. There is a calibration constant in the EBL BIN for injector #/hr that has
to be set by using a known quantity of fuel and adjusting the constant so that the trip meter agrees.

I've never been confident that I'm filling the tank to the same level at successive fuel stops, so I'll be running the trip meter over several
'fillups' to calibrate.

Probably, weighing the fuel when it is placed in the tanks, and measuring
the flow weight as it is consumed is the most accurate way of determining
remaining fuel, though it does not give you much of an idea of unusable
fuel in the tanks, which in a GMC, is considerable and varies by slope and
tilt of the coach.
No system is perfect. The only way that you can absolutely guarantee
you won't have to be lugging heavy fuel cans down the shoulder of some
remote 2 lane in the pouring rain, is to refill at 1/2 tank. But everything
in life is a learning experience. Some of you might enjoy that. But not me.
