Red low fuel light

[Kirby]

My red low fuel light has stopped working. What should I check? Is there a fuse for this? Everything else is working fine.

No fuse for this. There is a thermistor on the fuel sending unit that controls this. Its a temperature sensitive device. Gas is cold so when the thermistor is covered in gas no light. When gas drops below thermistor it warms up causing your light to come on. Either keep track of your mileage or replace sending unit for gas tank.

For me the light might come on and about 7-10 miles later would cough and have to flip to reserve. Thats what I went by, just drive off when you flip the petcock.

Thanks guys. I've been making it fine without it. I don't use the petcock unless I'm removing the tank, but I do use the fuel gage in the dash as well as the odometer. I'll probably just continue without it.

Same problem with my 05. I'll do the test to confirm the sending unit isn't working for the light side of the unit. If that's the case, I'll do the same...just go without. Maybe someday I'll find a unit cheap enough to make it worth my while to replace it.

In the meantime, I almost always stop for gas before 2 hours is up...as butt doesn't like sitting that long!

Mine quit years ago. I just use the reserve and the gas gauge.

I thought the low fuel light was amber, not red...

Makes one wonder why this part would go bad. Not much to it, I gather...

I can see after 20 plus years the gas would destroy the unit, but not after 10 or 12 years.

Wonder if I can simply replace the little thermistor? Probably not more than few bux to buy one.[/color]

Mine went bad 3 years ago. I live without the low fuel light now, gauge is still accurate, just no low fuel light or mileage countdown (never found the countdown useful anyway)

I honestly didn't know that there was a low fuel light. When I get to a certain low fuel level, my trip meter reading changes from the normal look to something like "F 000", and will start counting the mileage up with that F in front of it.

I guess either mine doesn't work also, or I have never been low enough to trigger the actual light.
