A little while back I approached Troy Hoffer of Superior 4Wheel Drive about a second gas tank modification. He spent considerable amount of time researching the request and came up with a phenomenal solution.

The DOT approved tank is fitted in the big space under the cargo area, next to the exhaust. The filler neck is accessed through a mini door in the bumper and there is a fuel pump that is manually operated to transfer fuel into the main tank upon demand.

A second fuel gauge indicates the fuel level in the aux. tank and an aluminum skid plate spreads the load in the event of impact. Total capacity is 19 gallons, doubling the range!

Fuel Gauge
----------
The second fuel gauge indicates the level in the aux. tank. The toggle switch next to it operates the fuel pump and the red light blinks on and off to indicate that the pump is operating.

Is this available to the market or one off. Contact and price info?
It is not a one off. Troy at Superior 4Wheel Drive will set you if you call him at (408) 448-8585.

He used my truck to come up with the design and I had a lot of other mods done by him at the same time. He requested that interested parties contact him for pricing information.

The filler neck presented some interesting problems. At first it looked like the neck would have to come out in the wheel well, but upon further reflection the bumper cutout became possible. Small details like cutting the door at an angle to maximize step area for the roof ladder.

Fit at Exhaust
--------------
The aux. tank seems almost purpose made for the FJ! It angles away from the exhaust to

tuck right into the space. Looking at it head-on you barely notice that there is something underneath the bumper. Overall, I'm pretty pleased with the way it all turned out.

That is awesome!!! I would be concerned with coming down on that hard on a trail though, i would probably go with a smaller one on my rig, but none the less that is one impressive modification!!!!

Yep, that is my biggest concern - hence the skid plate that will protect it somewhat. You like to wheel your FJ hard, judging by your posts! :beer:

I'm more looking at setting up a long distance expedition rig that a rockcrawler, hence the need for a long range fuel tank.

Troy relocated the charcoal cannister, I forgot where to. I haven't had the chance to get the car on a lift or jack stands to fully inspect all aspects of the mod...

Going with a smaller tank will get it up more, however, I think the gating factor on departure angle is still the trailer hitch. Its hard to tell from the picture but it protrudes very little under the bumper. Unless you looked very carefully you wouldn't even notice it.

yes but hi due not have a hitch and i have a highclearance bumper. I was hoping that a 12 or 10 would fit up there with less over hang so when coming down of that ledge or rock you due not wack it.


This is the best mod yet thanks for being the first hopefully we will have more with this soon.:beer:
