Do you think the FJ55 tank would fit in the space behind the axle in an 80 but turned around for the filler neck situation?
Fill on the FJ55 is also on the left side, so I'm guessing you just want to do a 180 to re-utilize the same filler opening, just plumbed to the right side to fill there?
Keep in mind that havings fillers on both sides is a bit of a hassle at the gas station, but a bearable one for no more often that it's an issue.
A big Maybe. The tank should fit in terms of width and length, as I'm not sure the 55 spare area would accommodate a 33" tire like the 80. Thus should be no problem there.
It was a deep tank, maybe 16"? The underside of the rear was angled to help with the departure angle. My guess is that this would be an issue, as I would think the tank would not be tucked high enough to allow the square end to be at the rear and not hang up, which would not be good on the trail with 50 gallons of fuel...
On the other hand, I don't think it would be too big a deal to blank the fill on the left and add one on the right. That would preserve the departure angle to the extent that everything else worked in your favor.
A little more, best I can remember -- I sold the thing nearly three decades ago.
I think it was a MAF tank. I think the bottom had a skid plate for more than just the tank wall in protection. It was mounted with four long bolts that went up through tubes built in the tank. I'm pretty sure I had to drill the holes in the floor in the cargo area to drop the bolts down through, but it's possible that it did mount via the original tank's mounts somehow??? DK, CRS
It was typical 70s quality construction. Unless you can find a NOS tank sitting in someone's garage or one that has set dry somewhere, best used as a model to build something similar. Mine had rust issues after a few years. Who knows what shape one would be in now.
Good to think about the tank. It's the sticking point to all this. Without it, shipping the rest from wherever you can source the OEM filler neck assembly, etc would be a lot easier and cheaper. If a quality US-made tank could be sourced, that would make this a lot more practical. I could care less about a tank saying Toyota on it somewhere, so long as it works and is safe. That's an issue with liability here, so may be the place everyone gets stuck on this. Getting a used tank that was commonly available here and can be reliably installed is probably the key making something like this work, even as a one-off, DIY project.
Reading the subtank installs, it's like joining an arcane cult. I can dig it, just not enough time and $$ for me to make it work with all OEM parts right now.
But I could sure use an extra 25 gallons. We're planning trips that will dig well into our 5x5 gallon jerry cansof fuel in the trailer at certain points after starting with the truck on Full. It would be a lot better to have it tucked away underneath, where I don't have to f with filling from cans, and where there's more space in the trailer.
Those LandCruisers get around Tibet somehow and I suspect that they don't take the same feed the yaks do. There's not a truckstop at every steppe, for instance.
