Home Forums Gear Hunting Trucks and Four-Wheel Drives Tundra Small Fuel Tank

Oldelkhunter,

You need to buy an SR5, and then add the SR5 UPGRADE, to get the 38 gallon tank. The UPGRADE deletes the front bench seat, and replaces it with bucket seats.

The easiest way to explain it to people, is to simply state that the bench seat gets 26 gallons. And the bucket seats gets 38 gallons. I doubt most people have any clue what the UPGRADE is.

If you prefer, state that the SR5 UPGRADE is needed. But what does that mean to anyone, especially when you don't even reference it correctly? You just make vague references, as shown in your post below.



I'm more interested in providing simple and accurate information for anyone that reads this in the future. I'm not sure what your motivation.

I don't own a toyota. But the 22 gallon tank in my 1999 chevy 3/4 ton with 6.0 leaves A LOT to be desired.

Where in your posts did you reference SR5 upgrade? Until I posted the pretty pictures you had no clue. Try to find a Tundra without the Sr5 package at the dealership that is not a work truck . Motivation Really, oh your from Oregon I see , no wonder GFY.

Maybe I'm missing something here, but what's so bad about having a 26,5 gallon tank on a Tundra? I'm on my 5th Tundra, and have loved them all, but by the time I run 26 gallons of gas out of my truck I'm ready to get out and stretch my legs. And fill up too. 38 gallons is a lot of weight to drive down the road too. Unnecessary for me. My 2 cents worth. Just sayin!

Thanks for reinforcing my point.

What truck do you drive?

He's right, you're wrong. There are plenty of SR5 trucks out there with 26 gallon fuel tanks, if you look inside them they'll also have bench front seats and a column mounted shifter. If you add the SR5 UPGRADE PACKAGE to your SR5 then the bench seats get replaced with bucket seats, the column mounted shifter gets replaced with a floor mounted shifter, the 26 gallon tank gets replaced with a 38 gallon tank, plus a couple of other small things like better steering wheel and auto dimming mirror.

To get the big tank you must at the very least have an SR5 with the SR5 UPGRADE PACKAGE, not the SR5 without the SR5 UPGRADE PACKAGE.

Yes, it's confusing but you're making it more confusing than it needs to be.

The SR5 is Tundra Model


On my first post in this thread I clearly said the Sr5 package not Sr5 model .

SR5 package has the 38 gallon tank



It was called either the SR5 value or upgrade package when I bought my 2017. He didn't bother to read my first post. I even posted pictures for him to look at describing it in detail. He just wants to argue.

Transferflow makes a larger aftermarket replacement tank or you can get a toolbox/tank combo with a transfer pump.

I have a 2017 SR5 with TRD package. 5.7L. It has buckets, center console shift and a 26.4 gallon tank.

There are no guarantees. Look at the build sheet and be sure...
or crawl under. The 26.4 gallon has two support straps, the 38 gallon has three.

You must not tow much. I towed an 8000 lb boat 1000 miles averaging 5 mpg and on my Tundra the low fuel light would come on when I had used 19 gallons of the 26 gallon tank, filling up every 100 miles sucked balls! It was a much needed improvement in the Tundra to put that bigger tank in it, as thirsty as they are when towing the 26 gal tank was a stupid idea.

Drafting and trying to maintain 6-7 mpg when I could!

When I bought my 2017 the local dealer didn't even know they had a 38 gallon gas tank available

If your tundra is an 07-15 why not go for 46 gallons?

2015 SR5

I had a first generation Tundra with 4.7 V8 and the small tank. I really loved that truck, but if I had to point to any bad feature it would be the gas tank size.
Mine got around 16mpg, so a tank would not last a week. I got a 4runner now, and it gets 21. That is a big difference, and I can get over 400 to a tank.

You must drive slow.

When I had the same Tundra I would get 18 on the highway. With the 4 Runner, 18 combined. Tundra 26 gallon tank. 4 Runner 23. What,1 less gas station stop a month? If one tops it off every time. Most don’t.


Addition: I can get 20 out of the Runner. If I keep it 60 and under on the TPK. Which means I’m not keeping up with traffic. 2016 and 65,000. The extra 2mpg isn’t worth the time lag over 65,000 miles.

And for most, it would be hard not to go by 15 gas stations a day.

Once you drive one with a bigger tank you'll never go back. I was in the market for a used truck (2012-2014 models) about 3 years ago and was leaning toward Tundra. But they didn't offer the bigger tank until 2014 and I couldn't find a Tundra that I liked, at a price I'd pay with that option. I ended up with a Ford instead. Even without towing the advantages are huge. Probably the best thing is that I can buy gas where I WANT to buy gas, not where I NEED to buy gas. It isn't unusual for gas to be priced 30 cents/gal cheaper 50-100 miles down the road. I can just keep driving through those areas where it is priced high.

The extra 10 gallons of gas is about 60 lbs. Not a big deal on a truck with a payload around 1800 lbs.

2016 5.7 litre 38 gallon tank

I have a 2010 Tundra with the 38 gallon and love it, that is until it’s time to fill it up at Costco and I have 3 cars behind me mean mugging me..lol
