I'm in the process of replacing my 3 fuel gauges. once new analog gauges are 
hooked up, i will pour in fuel 5 gallons at a time. Let fuel settle and take 
readings on gauge. This will give me a fairly close proximity of accuracy.  I'm 
using 1 gauge with a 3 pole rotary  switch to select which I'm using. Doug

gauge... Keep in mind that unless your tank has a flat, reasonably level bottom 
with 4 walls that are reasonably perpendicular to the bottom, ANY fuel gauge 
that relies solely on the depth of fuel in the tank will need to be calibrated 
since the depth of fuel of 1/2 tank is unlikely to represent 1/2 of fuel 
remaining! My tank slopes on the bottom along 2 different directions 
(athwartship and fore and aft) so a simple linear relationship does not exist. 
Further, until I had to replace the tank, my tank shape (except the top panel) 
was assumed to be rectangular but was far from it!Little reason to have a 
digital gauge Whose precision is up to 3+ places in light of a tank- gauge 
calibration which is much less accurate!Charlie NelsonS/V Water Phantom1995 C&C

Actually just a digital fuel gauge.    Tired of the analog being wrong (even 
after replacing gauge and sending unit).  Thought digital  might be more 
accurate.

Do you mean a fuel tank level gauge, or a digital fuel consumption gauge? The 
latter would be very interesting to have, but would require two flow meters to 
monitor the fuel intake, and the return, at least on most engines I think. It 
would
 be really nice to be able to watch consumption vs RPM in order to find the 
most efficient cruising speed. Looks like this one would do the trick, but a 
less costly generic meter might also be made to work.
