Low Fuel warning chime?

[WTITW]

Anybody know if there is a way to turn on a dinger of some sort for the low fuel light? I couldn’t find anything in techstream related.

Is your fuel low light working? I've never seen or heard of an audible low fuel warning before. I know when the mileage remaining on the binacle shows 0 (zero) miles remaining, I know I still have 10% more miles of whatever my tank was.
If one was clever enough (not me...) they could possibly tap into the sending unit and add a relay that goes off when the fuel level goes low. But one would have to know how the sending unit works. Is it like a potentiometer that as the level get lower, it reduces power to the gauge, thus lowering the needle? I'm just spit-wadding here.

Unfortunately....not aware of that one.

Was just hoping I missed something. I know it drastically underestimates the remaining range, but I'd rather just know when it hits a 30-40 miles left and have the range remaining be somewhat accurate. I never notice that light until it's been on a while, especially on road trips.

Be advised there are some reports of faulty fuel gauge sending units that stop responding at 1/8 of tank. I've generally seen this on 10-13 models.

Service history showed it was already replaced for that exact reason.

Jake: How many gallons have you seen left when fuel light comes on? I might be off here but I think most report around 3-4 gallons.

Just about that. When it gets to 0 range which is generally 20-30 miles after the fuel light, it takes right around 20-20.5gallons. I believe its a 23g tank.

That sounds about normal. There are a number of OBD fuel flow/usage PIDs I see with OBD Link but have never tested. I will see if I can find one that would at least be good backup to knowing how much fuel you have left.
