2nd Gen Non-Engine/Transmission Low Fuel Warning light

I just put 35+ gallons of fuel in my tank. The low fuel warning light/chime did NOT come on. Does anyone know if there is a way to check if this is a sensor problem or if the light is out?

Mine chimes in at about 28 gallons or so. Something's not right there. You might check your fuses first.

What did your fuel gauge show? I don't like to run mine that low because I feel the sloshing lets the lift pump pull air. And that cavitation is rough on any kind of pump.

Fuel Gauge showed an 1/8, maybe a hair under. I just looked at it, the light for low fuel comes on when you turn the key so it's not a light bulb. I checked the fuses but all I could find was a fuel relay fuse under the hood, was a type of Siemens fuse. Could that be it? I would think that would be for the LP, etc. I had just had the LP replaced.

I don't know what year truck you have but mine showed about 1/8 of a tank a while back and died. I thought it was the lift pump so I replaced it. Then I did just as you did and realized that the fuel sensor and warning light didn't work. Luckily I had a warranty and had it replaced. After replacement I let it go low to check it and as I was pulling into the pump the warning light came on and it took 26 gallons. Now I know that I have 9 gallons when the light comes on. It is your fuel level sensor.
