What causes the low fuel light to come on? A sensor in the tank or does it come on when the gauge drops to a certain point? I am just curious because usually it comes on when I have about 4 gallons left and yesterday it came on and I drove a little bit and filled up and there was still 7 gallons in the tank. When does your low fuel light come on?

when i have low fuel.

jk, but it's usually at about two gallons for me.

Yeah, most vehicles the light comes on at 2 gallons remaining. I wonder why mine is so odd

Were you on level ground when it came on?
It works off a float and because our tanks are very long being off level even a little bit is a big difference when you're low on fuel.

Yeah, Im pretty much always on level ground. And it comes on and stays on. You would think even if it came on because you were on a hill it would go off once you leveled out.

Just get fuel when you hit 1/4 tank then you never see the light..........

:lol3:that would mean I have to fill up more often and I don't like that.


Then again it would seem like Im spending less on fuel:thumbsup
