Does anyone have any experience with purchasing and installing a larger fuel tank on the FJ? I'm only getting between 220-240 miles to a tank. And most of that is highway. It would be nice to have a larger tank. Thanks in advance for the insight fellas.
 
I have a MAF tank and would probably go a different route in the future. The arm which mounts to the tank to the passenger side of the frame is cracking on every weld. I'm not sure if it was due to poor welding or if it couldn't support the loads it experienced the one time it met some rocks (Aluminum skid and tank itself are dented). Only driven it to the northeast twice and the amount of corrosion on the tank is quite surprising as well.

There is no doubt having the additional fuel is a great resource and convenient not having to stop for gas (I don't stop on roadtrips until I'm out of gas). Overall the system works well.

However, I will likely replace the tank with a proper fuel cell that has an internal bladder for improved safety in the future. I think there are some Australian companies that offer alternative tanks as well, but I'll probably go with a JAZ tank or similar in the future and make custom mounts and a proper skid plate (i.e. not thin aluminum).
 
We've had the MAF tank for a couple of years and love it. There has been no physical/weld failures at all and love the tank. We live in the desert with few towns around where we venture. The extra fuel range gives us a peace of mind that can't be explained.
When we bought, there was really no alternative for extra fuel tanks/cells. If I was looking now, I think there are more options out there. No matter what, if you want an on-board tank/cell, it's going to be expensive.
 
On every corner of the arm

Driverside of the tank came into contact with a rock once and wasn't that badly loaded. I was surprised how easily the skid and tank deformed. No idea if the welds cracking on the passenger side arm resulted from the driverside coming into contact with a rock or if it was just crappy welding from the get go.

There are several auxilary tanks out there from ones specifically offered for the FJ, to a variety of fuel cells which are generally a better product (require custom mounts), to OEM tanks from other vehicles which can be used.
 
Isn't that where they also believe just because a skid is labled HD (Heavy Duty) that it is really stronger. Obviously gusseting the same thickness of Al more than makes up for removing the steel backing skids on the normal Al skid plates ;).

MAF isn't a bad tank and is more than suitable for most stuff. Just didn't take to kindly to rocks. For the money I think there are some better solutions out there, but its hard to beat as a "bolt on" option. I do recommend painting it or coating it with something (anodize/powder) before installing them.

Like I said you can't beat driving 6 hours straight without stopping.

Here is another option:

:: The Long Ranger :: Toyota FJ Cruiser

I don't know anyone who has one though and I have seen no reviews.

My MAF tank has held up fine for what it is worth. I bang it on rocks all the time. The weld tears on FJNewbs are a concern though. Every time it is on the lift now, I check for damage.

edit: doesn't long ranger sound like a good porno name?
 
I'm not talking about it sliding over rocks. I'm refering to it supporting any of the vehicle weight whatsoever on rocks. The only time it has had too the tank itself (and skid) came away quite deformed. I'll get photos the next time I'm at the shop.

Like I said its not a bad setup, but far from ideal for rock crawling. Most folks use their FJC's on fireroads and general offroad trails which it is perfectly suited for. Heck Demello took a stock jeep liberty down on the trails at wheeltoberfest that the "heavily modified FJCs" thought were supposed to be difficult (MAF tank would survive fine on those). Puts things into perspective.

MAF tank is sound product for what most folks use the FJC for. That and the ranger tank are hard to beat for bolt on options. Just think that there are some better solutions for cheaper if you are willing try a custom setup.

Having new front tanks made ATM which will increase front from 72 - 96 lt, I have a 100 usable LPG tank under the back.

These tanks are to increase range when LPG is fitted, on petrol for remote travel.

What is it on this forum with random posters qouting exactly what folks said previously. This is the 3rd or 4th time I've noticed this in the past two months. The above was directly from my prior post.

Suspect they spammers trying to establish themselves with a few legitimate-looking posts so they don't get banned right away.

The product info in the link clearly states that their tank is NOT compatible with US rigs. I think it's the charcoal cannister location that is different.
 
Hmm, where is the difference between an US and an non US rig ?
Ok, maybe the australian FJ has litres and not gallons, maybe the odometer ist in km/h, but seriously .... I don't think that the FJ in the different countries have mechanical differences. :hhmm:

Well for one thing, Australian (and many other countries) trucks are right-hand drive. While this may not affect the fuel tank placement, it could well affect other things (such as the evaporation cannister as already mentioned).
 
I had a Long Range tank on the HDJ80 and the same tank was sold to fit the LHD and the RHD, the FZJ and the different HDJ models.
 
As said multiple times before - evaporation canister is in the way for the US models and thats why the Australian tank won't fit.
