Gas gauge strangeness

This may be well known to the LT gurus, but this is a first for me in 7 years and 43,000 miles. I filled my LT today as I have done hundreds of times. When I pulled away from the pump I noticed that my low fuel light was on and the gauge still registered about a 1/6th of a tank which is what it had when I stopped.

I removed the canister years ago so I figured it couldn't be a bent tube caused by tank collapse. And I was sure I had not gotten the pump nozzle too deep into the tank. I am very careful about this after reading the horror stories here. I was trying to figure out what might have happened when the light finally went out about a minute later. And the fuel level gradually rose to full after 5 minutes or so of riding. The next fill up was normal.

All I can think is that maybe I didn't get the key turned off far enough so that the fill up occurred "under power" and the gauge responded slowly using the "filtered" response rate rather than the normal "reset" during a fillup. Anyone else have this happen?

Re: Gas gauge strangeness

I've had that happen twice on my bike. Both at the same gas station(crappy unbranded fuel), so I just figured it might have something to do with the gas there. It hasn't happened since then. It happened before I yanked the canister, so I was sure my float tube was damaged, but all worked fine on the next fill up at my normal gas station.

Re: Gas gauge strangeness

Has happened every time I have not turned off the key when I filled and just used the kill switch so I didn't have to use the fob.

I don't believe I ever seen where I could extend the delay of the alarm setting so I didn't have to use the fob. I just need a minute or two longer.

I disabled that feature so I don't need to use the fob other than to manually lock or enable the alarm.

It sounds like that explains what happened to me today. Apparently didn't turn off the key.

Re: Gas gauge strangeness

I see something like this nearly every time I fill up if I let the tank go below 1/4. The gauge goes to where it was before filling, then over the next couple of miles, it gradually comes up to full.

I assumed it's just something sticky in the sensor that when it falls below 1/4 it sticks there for a while.

I've never noticed it when just adding a gallon or two.

If you look at the map and don't care where you are, you're not lost.

Re: Gas gauge strangeness

My gas gauge sticks. When I first start up it stays down at the bottom. After I flick it a couple of times with my finger on the dash it comes up and functions fine. Go figure...
