Thank you! I will dig out the Con-Ferr and see what shape it's in. If it's junk, I'll call Aero Tanks. I really appreciate it!

LRA offers a solution I'm considering (have their 12.5g tank on my 200)...

I question what changed between 1980 and 1981that it wouldn't fit in a 1981. I do know the FJ55 ended in 1980. Doesn't say it's for the FJ40. Doesn't say anything about mods to the vehicle to install. FJ55 requires moving the spare. FJ40 requires exhaust rerouting. 1/79+ the FJ40 has a CAT and 22 1/2 gallon tank which really makes installing a Muffler with a 22 1/2 auxiliary tank behind the axle interesing. FJ45 wasn't offered in the US after 1967. That one could require both the exhaust and spare tire to be relocated. Would need pictures and a whole lot more information before paying that much and shipping. Particularly being listed under Ford as the main vehicle. I know people will say mine isn't early than 79 but question why is listed to1980.

Unless they changed their design, Aero was the company famous/infamous for welding tubes THROUGH their tanks that required you to drill holes in your bed and HANG THE TANK from the sheetmetal floor with carriage bolts and fender washers!

Check the link on my post - its for the FJ40 and spans under both seats, replacing the stock tank. No exhaust mods needed as its inside the vehicle - not under/between the frame rails.

I bought a Long Range 29 gallon tank that replaces the tank under the passenger seat for mine.

No way I'd consider based on the method of installation, if still the same as their old system described by Mark in post #25. As an aside, I'm avoiding a tank mounted between the frame rails after discussing the safety issues with 2 Cruiser shops and my own experience. I got lucky with my last FJ40 - had the MAF tank and was rear ended, my leaf springs stopped the other vehicle from doing more than just a slight dent to my tanks skid plate (truck was SOA on 37's and the Civic that hit me went right under my rear bumper).
If you don't want to spend the money for what is currently available, take the dimension information from this thread and see what it would cost to build in whatever material you want. Post #11 and below is what you'll need.

I know of what you speak.
Full label was of another one made in 1977. Mine is CARB which would be newer and cruiser been off the road since 1988. Other than filling holes floor wasn't damaged.
my use will be diesel not gas first off
second, its not a pinto and no matter what I prefer the tank outside the cabin
ymmv

Those are pretty pricey and I'm trying to free up the underseat area for storage.

They aren't too far away from me. I might swing by and see if I can put eyes on one. If so, I'll let you guys know how it mounts and grab a few pictures.

No pictures of tank. No thanks.

Here is what left of my Datsun B210 12.5 gallon tank I put in back in like 1984. I just shook out a half cup of rust, I guessing its toast

The problem with the rear tanks that mounted with long bolts through tubes welded into the tanks was not cracking the sheet metal interior floor of the Landcruiser, it was that 22 gallons of gas bouncing in off road terrain cracked the welds where the tubes were welded to the sheet metal tank. Then you merely leaked your aux. gas all over the trail.
I have one of those tanks with the long through bolts that attach to the floor. I think there were at least 5 or 6 different manufacturers of auxiliary tanks for the FJ40 not including con-ferr and at least a couple of them used the same mounting method because I've seen some with 3 bolts and some with 4. I also did not like the idea of all that weight hanging from the tub so I modified mine to mount with straps and angle iron bolted to the frame.
I don't know what the fj40 tank looks like from aerotank, but I recently bought one for a jeep. Like I said, don't expect show quality welding and perfect straight corners, but they're functional enough. They were very responsive to e-mails, and I went to their shop to pick it up to save the shipping cost. They didn't have any pictures of the tank I wanted but I just asked for one and they sent it to me. My impression is that it's an "old school" 1-2 man shop that is probably more comfortable with walk-in and phone calls than e-mails and online presence.

Jim, if, by any chance you make more of your tanks, I'm a buyer. In researching this project, your tank was always the plan. I just waited a little too long to get started actually ordering parts.
