Hey guys,
For the first time tonight I found out there was a low fuel light on my truck. It has never worked for me, but when I was letting my heater grid cycle the light came on? I started and now it's off. I've got an 1/8th tank right now. Here is the real question, anyone got a schematic, so I could have this cool new light on my DIC (driver information center)
Thanks in advance

I think its supposed to come on real quick as a light bulb check when you hit the key, idk. i know it means you have 8 gallons left.

What do you mean on your driver information center? thats where it is? right next to the "anti lock" and "wait to start" lights?

The only time my Low Fuel light has ever come on is when, well... I'm low on fuel.

u can go a long way with the light on

The one time mine came on, it took 24.5 gallons to fill the 30 gallon tank.

Mine comes on when there is 1.5 gallons of fuel left. I have a 24 gallon tank which is kind of rare.

You sure? How did you determine your tank is only 24 gallons?

To Original Poster, my light has never come on any time other that when I am low on fuel, and I usually have 5-6 gallon left when it lights.

It says 24 gallons on the build sheet I got from Chrysler.

The amount of fuel left in the tank when the LOW FUEL lights is as varied as the drivers of these trucks.


Some will light with as much as 9-gallons left, while others will be sucking the bottom before the light comes on.


Personally, I cringe to think of distance travel with a main tank holding a mere piddly 30-gallons; my reserve tank holds 20-gallon.


I can't find it now; but, I posted sometime ago about filling the tank to a point above the light, then connecting an electric pump to the tanks DRAW nipple and pumping the fuel level down until the light comes ON and immediately stop pumping; then, with the pump-line in a seperate receptacle, draw it down until it will pump no more and measure what you have; although fuel will remain in the tank, the amount of USABLE fuel will be that in this receptacle.

For better accuracy, measure all fuel and pour it back in the tank, repeating the test three times, and average the results.

Pour this measured fuel back in the tank; measure the rest of the fuel and pour it in, immediately FILL it to FULL, noting the gallons; add these three amounts to get the amount of available fuel when tank is FULL.

Now, take your POOREST fuel-mileage(MPG) and multiply it by the USABLE fuel when tank is FULL; this figure is your RANGE WHEN FULL.

Then, multiply your POOREST mileage by the amount of USABLE fuel remaining once the LOW FUEL light comes ON; this figure is your remaining distance before the tank runs out.

Print this information on a nice card and attach it to the back side of the sun-visor.

There will be three or so gallons remaining in the tank, once the pump quits drawing fuel; and, although this amount of fuel is included in the factories declaration of tank capacity, it will do you no good if you can't access it.

Not in my truck. I have seen the light once and I never want to see it again. Took 29 gallons to fill the tank. YMMV
