I see I have a low fuel warning light on my dash but I have never seen it come on. When does it come on and for which tank is it for?

 

Not a light, just an icon. If you ever remove your gauges you'll see there's no specific bulb or LED or anything there.
Wish we had lights...

Unless you're a 96 then you might...not sure if the ODBII's had low fuel lights

 

We have low fuel lights? Never seen one on my 96, not even the symbol.

 

I think he was seeing the icon next to the gauge

I have a '92, just shooting in the dark about the newest of these trucks, thought I saw somewhere that they had them

 

Yeah mines a 96 5.0 auto, and the icon is just left of the fuel gauge. I was always scared i was going to run out of gas seeing if it would come on haha.

 

If it did, just switch tanks hahaha
I never thought I'd like dual tanks as much as I do...It's real nice

Someone somewhere was talking about wiring up some sort of low fuel light. I usually just dont let red show on the other side of the needle before switching tanks then filling up.

 

yea my 96 has the fuel warning light too, i forget what it was used in, i wana say it was used in the f250s or 350s or something.

 

And it works? bastard haha. probably for the diesels or something crazy.

 

mine dont work, i wish someone would find out what vehicle had a working low fuel light, im sure you can wire it in but i hate wiring lol. i cant find much info on the dang thing.
