my dad had a 2003 fx4 and his light came on at about 1/8th tank left..mine never comes on..so i drove it below 1/8th tank..it was actually on E to try to get the light to come on..never did...so i got scared and went and filled up


is it just on some that have the light or all of them?

mines a 2002 xlt

 

my light comes on once i get right to the beginning of E almost. i try not to run my truck below a quarter tank though

 

i dont like to run mine down that far either, but i didnt know if it worked or not so i didnt know if mine worked or not.

 

I have had mine on once. It comes on right at about the E. Something I dont ever care to see again.

 

Your bulb is probably burnt out doiii

lol, yea, it's behind the cluster, twist and pull. You might be able to swap it with another behind there. My fuel light bulb hasn't went, that I recall, but others have.

Just above E on my 98.

 

turn your key to the "ON" position without starting the truck and all your Annunciation lights will light up. if the low fuel light isnt one of them, its blown. refer to my cluster color change swap if you need help removing the cluster

 

that light came on in my truck once, and that is before I even baught it. Long Story. We (me and my parents) went to the dealer to see about getting me a new vehicle (85 olds at the time, tranny was going) Me and my mom had been there 2 days before and had the options of either a dodge dakota r/t low and black or a red dodge 1t 3500 Dually running gasoline, went there 2 days later with both parents (dad had better crdit so he bought the truck in his name) and the dakota was gone and dad said no to the 1ton. They just got the 150 in so we took it for a test drive, while going around the block we noticed the "Low fuel" light was on and the needle was on empty. we got back to the lot, shut it off, and said we'll take it and when they went to start it to give me a full tank of gas it wouldn't start so they had to get a gas can to get it to start.

 

it lights up when i turn the key forward

 

my gas tank is 24.5 gallons. my light comes on after burning 19 gallons. so i know i can go pretty far on E, maybe about 16 miles


blahahahaha

 

yah mine comes on with about 5 gallons left

 

Then the light works.

You can always carry a 5 gallon container of gas around with you then run it until either the light comes on or you run out of gas if you're really determined to see how it works.

 

I've only seen the light once with my truck running, personally I'm a fan of keeping more than a 1/4 in 'em at all times...


I would not run it that low (expecially in cold weather) but it's your truck your choice...

 

I don't rely on the low fuel light.
Instead, when I fill up I hit the trip reset on the odometer.
Then I know when it reads 400 I'm about to start walking.
When I do drive the truck I know about what my round trip will be.
I always check the trip meter before I leave the house as the gas stations I frequent are near my home.
If the trip meter tells me I don't have the miles remaining to make it back to home base easily, I just fill up before I leave.
Uusally the math works where the low fuel light will come on in the process but, I pay it no mind.
I don't drive the truck everyday so this simple process has served me well.

 

like i said, i was just trying to see if it worked or not, i normally fill up when i hit 1/4th of a tank


and im not gonna run it dry to see if the light will ever come on, im not that determined.

 

guess it does work!! it JUST came on when i took the picture..damn you have to run this one low before it comes on
