Tundra 46 gallon fuel tank

[ottorogers]

Just sharing my recent experiences with the 46 gallon fuel tank, Transfer flow no longer makes the 46 gallon replacement tank for the Toyota Tundra (I called the factory today), many of us have the Tundra with the Hawk and Grandby FWC. And many of us have the very small 26 gallon fuel tank (no idea why Toyota did this), the other company is called long range automotive in Australia, they apparently make a very good 46 gallon tank, in some ways better than the transferflow (which is discontinued), but, and this is a big but, they want $1595, plus shipping from Australia, and installation, which is ridiculous in my opinion, last January I was quoted $1295 from Transfer flow in California, free shipping to Arizona, but I could not find a dealer to do the install before I left for Texas, the total I was quoted out the door was $1650, which is very high, but I was willing to pay it, but could not make it happen while travelling around last winter. The Long Range unit from Australia is $2200 or so including installation, shipping and the tank itself, NO WAY I AM PAYING THAT MUCH. Does anybody here know what the cost is for the Toyota OEM 38 gallon plastic tank? It has a huge advantage, is is very light compared to the steel transfer flow.

US gasoline fuel tank stds are fairly stringent. Diesel tanks are less so, which explains why you might be finding that the US aftermarket supports extended range diesel fuel tanks and doesn't have much for gassers.

TF is a bit notorious for that, not carrying a product in their line-up for very long. Have you thought about seeing if there is any new old stock of the TF tank? Maybe one of their vendors has one.

There is a previous thread on this topic and I thought someone had posted in it that they had priced out the OEM 38 gal tank and the related required hardware.

Another option is to have a stainless tank fabricated.

I wonder if it is possible to get a plastic tank made to fit the exact way a very heavy Transfer Flow would fit, it would be 100 LBS lighter???

Probably not possible for fuel. Plastic fuel tanks are blow-molded with rounded corners out of cross-linked polyethylene. I suspect this is to survive the drop test requirement. I'd be rather surprised if a plastic welded tank could survive that test and I personally wouldn't want a gasoline fuel tank that couldn't survive it.

I have a 46gal transferflow tank for a tundra I'm not using in San Diego if anyone is interested.

Is there any way to stash a 2nd tank somewhere under a Tundra?

I think you’d need to replace the whole tank. My 2017 has a 38 gallon tank which is an option so the space is there. A friend of mine bought a used 38 gallon tank from a junkyard for $500 and is in the process of gathering the other required parts for the install.
