[MENTION=76419]Doc2012[/MENTION], I'd be happy with a 26 or a 25 gallon tank.
Titan Fuel Tanks - Potential for 30+ Gallon Gas Tank for 3rd Gens?

This thread is a Dream killer as I'm trying to figure out what to do with my spare tire area. The area is nice and low for the weight of an extra gas tank. It seems more economical to have a rear swingout bumper with two 5 gallon gas cans. ~17 + 10 = 27 gallons. Not that bad.

the issue with a single large tank and only half filling it is you would need to baffle the tank significantly, other wise you have all that fuel sloshing around in corners and braking/accelerating. -yes most tanks have baffles, but they are typically smaller tanks thus requiring less baffling and less intricacy. i think dual tanks is the way to go here. you have a single aux tank that is say 10 gallons at 15mpg(thats ave for most of us who would like this extended range) thats 150+ miles you add that to 250 mile range you already have and you are at 400 miles. then if you want you can add another 10 gall in jerry cans. another 150 miles for a total of 550 miles. fuel at 7lbs per gallon would be 140lbs for 20 gallons that would be 360lbs of fuel total, plus all the gear you will be taking with you for the trip -tools, food, camping equipment, and then you have all the armor (skids, sliders, bumpers ect). pretty soon you have come to a point of diminishing return. the truck will be so heavy, the motor will be working so hard, your fuel mileage will suffer drastically and you start losing range fast. how much weight to most people take with them? i know for me when i have gone on multi day trips where it would have been nice to have more fuel capacity in the past, i am close to 6000lbs, way over what this truck was ever intended to carry. i really think a smaller tank (15 gallon max) is the best bet and would work wonders -much easier to tuck away, and protect, and it helps keep the weight down while giving people added range.
-toyota never designed this vehicle to be a work horse, or overland vehicle. if you want one of those get a 80 series land cruiser. this was a vehicle made for soccer moms and people who wanted the appearance of a rugged vehicle. not to say it cant be rugged or good off road, but that was never toyotas intent with this truck.

the great him,
OK... that makes sense. Do you mind if I ask how much you paid for it? Did he sell it with everything he had done or did he reverse some of his mods?
Dirty Fingers,
I'm with you, but I would want 29 or more... anything to add to 18.5 would be beneficial, which as I mentioned earlier is really closer to 17 because of the known design flaw that for most owners keeps it from filling all the way up to capacity. The 20-Litre jerry cans that many owners use holds 5.28 gallons of gas, so a gas tank with a useable 29 gallon gas tank equals the 18.5 factory tank plus two 20-Litre jerry cans.
Why can't something be designed for our 4Runners that is similar to the saddle-shaped 18.5 gallon gas tank in the 5th Generation Corvette? There is some type of tube or return that ensures that the two "sides" of this tank function as one. Could a replacement tank in the stock tank location have a return or tube like this that connected to another tank in the void left by removing the spare? The key is to have these two tanks function seamlessly as one tank. If this were possible what type of capacity are we taking about here?

Oh, snap! That's bloody brilliant!For those just wanting extra fuel on a expedition you can use two Bladder Tanks of 18 gallons each.
Gives you two fill ups and about a 800 mile range.
I used to use them for my Boston Whaler.
Once empty they roll up out of the way.
I had two "Nauta" bladders, worked great.

Well they worked fantastic on my boat, I hooked up a fuel line to each bladder and had one on each side of my boat about at midship.
I had 2 outboards, so hooked each one to an outboard and ran off the bladder tanks first.
That gave me a 36 gallon boost so that I could get out on the other side of San Clemente Island in Southern California (65 miles out) and then have a FULL tank once I got there and then just roll up the bladder tanks and stow them away.
I also used them when I would tow my Whaler down to Cabo San Lucas with my old Ford Bronco, this was back in the 80s.
That road back then was treacherous and didn't have very many Pemex stations so I filled up the boat built in tank with 63 gallons and then the bladder tanks with an extra 36 gallons.
The bladder tanks were about 110# full I think, nice handles on it so was easy for two of us to hold the bladder and empty it into the trucks tank.
Should work just as well in a 4Runner if all that is needed is just extra gas on hand.

So did anyone try to fit a LC 90 tank to the rear of a 4Runner? Or would the spare tyre winch crossmember need to be removed?

They made Petrol Landcruiser Prado/Colorados too.
Funnily enough I have a friend with a Landcruiser Colorado who is looking for a 3rd gen surf/4runner fuel tank to do this the opposite way round.
Not really be an issue for me... The UK is too small to run out of fuel :thumb:

I had a 1994 LC, on 35's, 5.29's,linked front end, plate bumper, etc., and it pulled no better than 13mpg, usually more like 11. I had to fill it up every other day. At least with this runner I can get 300+ miles out of a tank, instead of the 200 I'd get to 1/4 tank with the FZJ80.
The LC was pretty awesome for a 5600lb vehicle, but it didn't make sense to me as far as an expo vehicle. There are guys on mud and the expo that have added the ROW aux tank, but it's an ordeal and it's not cheap. The way these rigs work best is with a turbo diesel, but you better not be in a hurry to get somewhere. :sleepy:

The 90 series LC Prado shares a very similar chassis with the 3rd Gen and has a fuel tank mounted behind the rear axle.
Note how Toyota puts the last frame crossmember at the very rearmost section of the frame as opposed to the location of the crossmember used to support the spare tire winch in the 3rd Gen. I'm not sure if it supports the tank in the Prado as well. I would look into finding the measurements of the frame behind the rear axle to see if they are similar lengths. If they are, then this may be a very good option.
That's where Toyota should have put ours. I'm probably just going to make my own tank to sit back there with a 1 1/4" tube frame under it to act as structure and a skid. I've already added a rear crossmember at the very back of the factory frame and am putting the spare tire on a swing out.

True enough....which is why you want some significant structure back there if you're going to put in a tank at that location.
That's as simple as a good, stout bumper....likely with a removable drop hitch and or a tubular type skid (plating is optional IMO) and a tank out of at least .090 steel welded inside and out and potentially with cross sectioned baffles to strengthen the interior.
