Tundra low Level Fuel Light

I have a 2012 Tundra. The low level fuel light that has the arrow pointing towards the left has decided to come on even when the tank is full. Any idea's? It's the light under the full mark on the gauge.

I can't believe you just posted this question. 

My 2010 Tundra ran out of fuel about two weeks ago and I had to spend about $1,000.00 for a new float to tell the light switch to turn on and for a new fuel pump.  I am very good about waiting for the fuel light to turn on and then I would reset my trip meter to zero and then I always knew I would have about 70 miles before I had to refuel my vehicle.  My problem started when the float failed to turn on the light switch.  When the light switch did not turn on, I never reset my trip meter.  Since I never reset my trip meter, I had no ideal my fuel was low until I ran out of gas!  And as you would expect, I ran out of fuel at the worst possible place and time on a very busy freeway with a narrow shoulder and an night with no street lights and traffic flowing at max capacity.  Since my fuel light never turned on, I never suspected that lack of fuel way my problem, so I call a tow truck to move my truck.  The shoulder was so narrow, that the tow truck driver and I had to crawl out of our passenger doors to get out of our vehicles.  Also, he would not load my truck onto his tow truck until a second tow truck arrived to shield the loading of my truck by parking behind my truck.  

Once I got my truck to the nearest dealer for repairs, they added a few gallons of gas and it fired right up.  My truck normally gets about 290 to 300 miles per tank.  My trip meter showed 367 when I picked it up after the repairs.  So, the trip meter was about 60 to 70 miles more than when I would normally refuel once the low fuel warning light turned on (if it were working).

Again, my repair consisted of a float to control the light, and a fuel pump.  If you're lucky, maybe all you need is the float.  Otherwise, it could be up to $1,000.00 for repairs.

Note: This is the first time my truck has ever stranded me on the road.  Also, I have about 110,000 miles.

Good luck.

The gauge works it's the stupid light that's on. It started happening after I filled it up with a half tank.

My gauge was working as well.  It was the float that controls the light that was bad.  Good luck.

Yea, it might be a remove the bulb deal. I'm not spending that kind of money for a light to turn off.

Try the easy stuff first. Have you unhooked your battery cable yet?  If not, I’d try that. Leave it off for 29 minutes.

I hear those floats sometimes stick. Leave it alone for a bit and it might knock itself loose.

8yrs 120k miles in my 2010 5.7L.... never heard of anything like this.  Never ran it empty.

towing an 8-9000lb boat, I will absolutely not pass a gas station past 1/4 tank getting only 6-7MPGs.

and I will never buy another truck with only a 24gal gas tank again.  Garbage.

^^^haha preach!  My last truck had a 36 gallon tank so when I was shopping last year for its replacement I never imagined I’d buy one with only a 22 gallon tank, talk about facepalm. I used to be able to get to the lake on one tank (~350 miles) and now I can’t, sucks!

I agree with Ryan and Falko.

In some regions, the Tundra can be had with a 38 gal tank.  I travel to OKC often, and most of their trucks have the option.  I couldn't order it here in St. Louis...

I just put 25 gallons in mine with a 1/4 tank showing on the dash. Newer ones have larger tanks?

I'll do the battery cable deal first. I snow ski a lot so maybe this winter driving to the mountain will knocker loose.

As long as we are comparing tanks, mine is 95 gallons.........................

I honestly can't imagine having a tow vehicle with a tank that is 25 gallons or less.  Kind of silly to equip a truck that way, but I am sure that the manufactures are doing it to save weight for better MPG ratings.

Mine F150 has a 36ish (?) gallon tank. Biggest tank i have had in a car. Problem i have here in Ca. is gas is ~3.50/gallon and the stations only allow you to pump $100 at a time. Sucks that i can't even fill the tank if I'm close to empty. If i want/need to fill up, I have to slide my card twice. Sucks.

Used to have that problem, but since gas is less here in Alabama, I don't anymore.

Weird that this is going on - have you checked the Tundra forums? 

www.tundras.com 

or

www.TundraTalk.com 

 

Not that this helps solve the issue, but the fuel pump is cooled with fuel, so that light might be indicative of a blockage or failed sensor somewhere.  Good Luck!

Meanwhile $2.20/gal anywhere in my town.
