Confused after fuelling up

[tonto]

So I was running low on fuel before the end of the week (payday!) so I decided to throw in $15 to make it through Friday. My low fuel alert came on (80km until empty) so as usual I just cleared it. After fuelling, I started up and the low fuel alert came back on, still displaying 80km until empty. Normally, this doesnt happen, so I decided I would drive around and let the fuel gauge catch up perhaps. Nothing happened for the 5km I drove and remained like that until the following morning where the fuel gauge kicked up and the display read 160 km until empty. Was this perhaps a hiccup in a sensor?

if i leave my truck running when i fillup it gets messed up. needs time to "learn"

$15 is like a drop in the bucket these days! I would be suprised if the needle even moved. LOL. I know if I fuel up and leave the engine running, the gauge doesnt register until I shut it off and re-start.

If you leave the truck running or have the key turned on/acc when putting fuel in, it will mess up the gauge reading. To correct this you can disconnect the batteries for awhile to reset the memory.

You don't have a problem,your truck is very thirsty and you only gave it a tiny sip. The owners’ manual makes some note of the phenomenon you mentioned. If you fill it up more after an ignition cycle you will see the gauge move. I would be more worried about the injectors or sucking crud from running the tank that low.

All I know is that my needle moves with the fuel level when I'm fueling.

Definitley great tip, I filled up right after I read that lol.

After working at a Fas Gas for years in my teens, I was always told to get both diesel and gas owners to shut off their vehicle while fueling, and I'm pretty sure it's illegal in Canada to do otherwise?

I never shut my truck off while fueling. The needle moves with fuel i put in. I also very very rarely run under 1/4 of a tank for fear of not finding a station before i start gettin low. Last thing you want is to let those injectors run dry.

My 06 does goes right up. Driving an 03 not too long ago, I noticed it did go all the way up until I shut off and tuned back on.

I had it happen once and my truck was off during fueling. I was pissed and drove around hoping it would come to life. It didn't so I went home, in the AM when I got in it was back to normal. No issues since.
