'96 1500, I always run the tank low when i'm just riding local. Usually use the low fuel indicator to alert me to start looking for fuel. So, long story short, ran out of gas.....was about 5 miles from the house, so the wife was nice enough to bring me a couple gallons of gas. Less than 15 minutes later, I was on my merry way.

I didn't think to check the low fuel lamp initially, assuming the bulb had burned out. On the second or third key on cycle after getting the roadside rescue, I noticed the LFL came on with the other dash lamps for the few second test when you turn the key on.....WELL looky there!

So I continued to run the last of the 2 gallons, give or take, out of the bike to see if the lamp would come back on at the low fuel level......no luck.....out of gas the second time.....(I had a spare gallon in the side bag this time!)

So, What gives? Can I change the LFL sensor separately or do I have to replace the whole in tank unit?

The low fuel sensor in the tank is bad. The light bulb comes on when you turn the key on is a test of the bulb, not the sending unit.

Probably the thermistor in the tank is bad. Somewhere on the web are instructions to replace it.

I have some thermistors. Come get one if you want.

Here is a pdf file of some instructions I saved from a thread about replacing the thermister for the low fuel light. No pictures but if you take the fuel pump out you should be able to see what they are talking about.

Pump pulls fuel from the bottom of the tank anyway, so if there's dirt and debris in there it will get pumped into the filter whether the tank is full or almost empty... Doesn't matter.

I never rely on the gage or low fuel lights. Comes from being a general aviation pilot I guess, as small aircraft gages are typically considered unreliable. I frequently calculate the mileage and have a high mpg and low mpg figure that I use to determine fuel stops. On the highway, when I hit 150 miles, I need to be in front of a gas pump. Local and slower roads, I use 180 miles. Have never run out that way.

I do the same. The gauge is just a backup. On a long trip I start looking for gas a 200 miles.

Can't read the trip meter without glasses anymore, but after the fuel needle has been a quarter inch past empty for about 30 miles or so you kinda start seeing the Low Fuel light (if it's a cloudy day or at night). Can't rely on the low fuel light (too dim to see in daytime) so I just consider the 1/4" past empty point a good time to get fuel. That's usually a 5 to 5.5 gal fillup.

One of these days when I have the tupperware off I'll get into the tank and bend the float arm so the gauge reading makes more sense.. Thinking I'll also convert the low fuel thermister to a float (there's a thread on that here or on 'Docs, somewhere).

Of course, the 1100 is (and my other past bikes, too, for that matter) much less ambiguous about low fuel. Its gauge stays on empty a long time, too, but when you're down to reserve there is absolutely no doubt. (Except for one time when I reached down and discovered "That WAS Reserve!") :ROFL:

None of my bikes before this one had a gas gauge, Mileage is the key. Of coarse on the OLDER bikes you had to do the "switch to reserve" dance at 60 MPH on the highway in traffic! That was always fun and taught you to learn to use the mileage as an indicator.

Why push it so close to empty in the 1st place? I start looking for gas just below the 1/4 tank mark.

I've rode my wing for Commuting, more than leisure; typically 70 miles daily.


I had my fuel consumption so perfectly worked out, that I could fill up every 3-days rather than every 2... which I was able to do by Riding the Same Route, at the Same Speed (under 65mph) every day. I'd typically reach the gas station with under 10 miles remaining in the tank. That "extra day" of gas saved me ~4 gas stops a month, or about an Hour of Time... which was the carrot for me. :laugh:

I run the fuel level down low so as to get more miles per fillup.


I also carry a 1 gallon leak proof Jerry Can "just in case".
have never run out of gas, have at times topped off at 5.9+ gallons


I use the GPS in "Look Ahead" mode to see how far the next gas opportunity is.
then compare that to the tank reading, which I have calibrated by pouring in exactly 1 gallon of gas to see where the fuel gauge reads.


for everyday riding? I fill it up when I get home.
