    You can get 38 gallons out of this tank, it's just a question of what perceived damage is being done to the fuel pump by running it dry. Why did Toyota set the low gas warning to come on at around 8 gallons left instead of 3 - 5?

    So the media wouldn't see a bunch of Tundras parked on the side of the road due to running out of fuel.

    I'm sure it has something to do with percentage and mileage. They likely either want you to be able to go X# of miles after the light comes on, or with a certain percentage of fuel remaining (or both).

    I would lean toward percentage. 3/21=14%. 14% of 38 would be 5.7 (almost 6) gallons.

    All I know is I’m glad there’s a large cushion ... wife gave me some bad navigation on our last road trip and I had to make another 25-30ish miles after the low fuel light to get to the next gas station! Don’t recall exact count, but I think I only filled up 33-34 gallons.

    Typically I am at 31 gallons if I hit the low fuel light.

    It's based off of how many miles you can go after the fuel light on. Not how many gallons are left. Wouldn't make sense to only have a 3 gallon reserve and only have 45 miles left when a honda civic has a 3 gallon reserve and has another 120 miles to go.

    Oh really? When was this standard decided by Toyota / Auto manufacturers? Just sayin' because my '06's light came on when it had maybe 3 or 4 gallons left. Does the smaller third gen tank warning light come on when it still has 8 gallons left in the tank as well?

    Brand new 21 CM. 15 miles left on the estimated tank, and truck stalled in the driveway angled down when trying to turn the engine over.

    Had to roll down to a flatter spot on the driveway to get it to turn over and stay over. Went to the gas station and put 31 gallons in.

    So 7 gallons remaining and it stalled out? This is extremely disappointing.

    30.5 gallons was the most I have put in so far. That was on a deer lease trip where I was trying to push it, stupid as it was as towns are 30 miles apart.

    This is why. The tank is tall and long, and the pickup is near the middle. All your fuel was at one side of the tank. The larger the tank, the bigger this issue is. It's about percentage volume in this scenario. If you have a huge 100 gallon tank and you have 10 gallons of fuel, unless there's baffling in there, the fuel won't be high enough for the fuel pickup. The fuel pickup in the Tundra tank is about 1" above the bottom. If your fuel level isn't more than 1" high in the tank, below the pickup, you're not getting fuel.

    Does anyone know if the stock tank is baffled? I had the smaller tank and didn't check for baffles before installing my TFT.

    I’ve only filled it a couple times, but it has always been around 32 gallons.

    When it reads zero miles left I still have at least 5 gallons.
