Day before yesterday my guage was below empty before the low fuel light came on.  I said I had 22 miles left, at that time.  I stopped and put gas in it at 9 miles and it was way below empty (the lowest mark on the guage) at that time. :nixweiss:  By the way, that was 205 miles on the trip meter. 

Seems to be a standard Harley Davidson guage to me........none of them have ever been accurate over the years on any of the bikes I've owned.
Hey JC, do you happen to remember how many gallons you put in when the gauge was reading below empty? :nixweiss: I'm gonna guess 4.7 gallons.   ??? spyder

Mine took 4.1 and the gauge was on the line above empty.

That would be about right as JC said his was reading way below the last mark (empty).  I'd do the incremental fill-up a gallon at a time, except at my age I'd promptly forget.. ???...so why bother?  :drink: har!   spyder

I carry one all the time....not for me. Just in case someone gets stranded.

The best thing to do is.......never turn down a fuel stop. I learned that a long time ago.
May sound stupid but it works for me.

I guess I will go to the "E" next time and see what happens....

On my O8 street glide I could consitantly get 250 miles on a tank...unless I rode her at 80+ miles an hour for long distance.  the fuel reserve would go on about 32-34 miles...(suppose to mean 1 gallon left) then when it gets below 10 miles left it just says "R Lo" get gas extremely soon.... I have gotten to that point way to many times... also if you are at 44 miles remaining  and going 85 or better... it will decrese 2.5 miles every mile you go....I have seen it go from 44 miles to 15 miles left in like 6 mins... I have also put in 5.938 gals in the tank once.... and no I did not have to push the bike thought I would but I did not.... I should have drove around the gas staion till it ran out...

I'm still comparing my gauge to miles per gallon calculations using the trip odometer.  My gauge was just above the "E" mark and the DTE said I had about 59 miles left when I filled up.  I put in 4.5 gals and had 181 miles on the odometer for right at 40mpg.  Don't know if the mpg will be that good once I get it broken in, but we'll see.  I do think the the gauge on my 08 Street Glide (with the 6 gal tank) was more accurate than this one is.  But the DTE appears to be fairly accurate, so I don't think it's the float/sensor as much as the gauge.   :nixweiss:

I feel that the DTE is more accurate also. So the float is supplying the correct signal and the gauge is just reading incorrectly while the DTE is reading right--I hope.

Gas gauges and air temp gauges are no more than idiot lights. I can ride 160 miles on half a tank, and then 40 miles on the second half.  Use your odometer as the gauge. HD doesn't put any QC in that stuff.....never has...

Was the gauge on E and for how long before the light came on?
