A capacitance fuel quantity system is the most accurate and reliable as proven by just about any decent aircraft in the last 40 years.

Re: No Fuel Gauge -- What Approach Would you Take?

On our boat we have a fuel gauge, but the tank is rather flat and as such the reading is not reliable.
I used the engine manufacturers fuel consumption chart and then the first few times we were out cruising compared the calculations with the actual usage (must run a consistant rpm for this).
After a few trials I was able to comfortably calculate our fuel consumption with remarkable accuracy.
I did these test durring several trips at different rpms.

As a side note I try never to run the tank all the way down (calculate a good reserve).

Lest we lose sight of the big picture we are sailboat drivers, right?

I mean can't we just sail to a gas station if we run out or have we forgotten what those big triangular napkins are for - LOL...

Fill your tank. keep a log of engine hours and fills. (Date, gal's to fill, engine hours) Soon you will know your burn rate.
Sailboats use fuel so slowly the problem is more how to use it to get fresh fuel in than running out!
You will burn probably somewhere between, .6 to 1 gal per hour.
So if you have a 100 gal tank and burn .75 gal per hour at 7.5 knots.
That's roughly a 1000 miles or 135 hours of motoring full speed.

Delightfully simple.

You even get to use high school math!

It's pretty foolproof, too.

Except for us fools who use it.
