Titan high capacity fuel tanks

And for this reason that's why CBI is likely resistant to making a commercial product for their bumpers. It just opens up a ton of liability.
 
I recall the same thing happening when I had my FJ.
US laws are so strict about fuel tanks that the FJ had to have a transfer pump to move from the aux to the main. Needless to say, they were not DOT/EPA/USG approved for us.

Hope it works out with Titan though.
 
I say we still blow up the request. If there's enough demand, then they would find a way around the laws. There's always a way to get something done. They do have a option for jeeps that go in between the rear tailgate mounted spare tire. Maybe something like that would work for us.
 
Might like to check that out. generally 350 is good enough (A lot more than early gens!) but when pulling a trailer or going on a long back country trip, having a 30-35 gallon tank would rock :D

I live on a small island so I may be a bit naive when it comes to vehicle range issues, but wouldn't just carrying some 5gal jerry cans be a much more economical and simple solution to this problem?

Usually that's the case. If CBI made a production version of their rear tank I might consider a half-sized version. But I've never ran out of gas while off road. Water yes, but fuel? no.

Yes, if you have an aftermarket bumper or roof basket to carry them on. My stock 5th gen has no carrying options other than inside the vehicle which is illegal and unsafe. I was really getting excited about a larger tank :(
 
After reading the email from Titan, he never specified a replacement tank that replaces the original gas tank. I'm still hopeful for a larger replacement fuel tank. I still think they could produce one within the current laws.





Bad news friends, I received this email below from Mike Deford, Marketing Manager from Titan Fuel Tanks this morning. The email explains why its very difficult to make replacement gasoline tanks vs disel within the law/regulations. Check it out below.

Re read his message. He said it is virtually impossible to make a replacement tank or an auxiliary tank. If there were a way around the law it would have been done for Jeeps. Liability is the key here.

This has been tried before several years ago with a manufacturer. I think one member fabbed up his own tank to fit in the spare tire location. Pretty sure there is only that one example.

CBI did it as a one-off:

I read the laws, and I don't get how an aux tank is illegal. That said, it's quite possible there are official "interpretations" by the EPA that expand on the laws. Actual tank manufacturers would know more than I do.

I understand no gravity feeds (overfill and pressurization problems, plus leakage in wrecks), but I don't see why you couldn't have a small pump move the gas from the aux tank to the main tank. You may have to pump into the main tank filler neck instead of the tank itself, but it should be workable.

OEM Dual-tank filler necks exist for the Land Cruiser which can be installed on the 4Runner, but I understand they are hard to acquire. It has a single cap and the tube has a "Y" junction with a flap to divert the fuel into the correct tank. The flap is controlled by a knob.

The Jeep tire-carrier tank is essentially a mounted Rotopax. It isn't connected to the main tank in any way; you have to manually transfer the fuel using a separate siphon/pump.
 
Again it's a liability reason. I guess the liability of an offroad bumper isn't as great as altering the fuel system, but I can understand why CBI and other companies don't want to mess with it.

Jerry cans for the win.
 
BS. GenRight makes aftermarket oversize GAS tanks for Jeeps. Transferflow makes oversize GAS tanks as well. Keep trying, they can be made.
 
Why not a pre-fab fuel cell (vs a totally one-off custom tank) in the factory spare location?

Same issues/effort with filling and transfer but should be way cheaper, easier, and safer.

Or is there something I'm missing or hadn't considered?
 
I know the Prado Kakadu has an auxiliary tank of 63 litres. It might fits. That's like 2/3 of the main tank in extra fuel!
 
I want a tank where the spare tire was. I don't need another pump. With compressed air and a little work, I can transfer the fuel to the OEM tank. Keep it simple and cheap. Simple is easy to fix and maintain on the trail.
