Auxiliary or Larger Gas Tank

[AnthemAVM]

Just got back from a 2,500 mile trip and would have been nice to have a larger fuel tank.

Spoke with a rep at Long range America. He said they manufacture in Australia and the GX will show up soon there. At that time he thinks they will make an "Auxiliary" tank with a transfer pump. There will be switch and a gauge for the extra tank's level. When the main tank gets low the driver switches on the pump to fill the AUX tank. The reason for this clunky fix is because Toyota will not allow even their master tech's to mess with the ECM to allow a new volume of gasoline to be recognized.

It will likely be pretty similar to the build of my 80 series with their tank, which was imported by Man-A-Fre. That required removal of the spare tire and its repositioning. This link is to the placement on my 80 series LC.

Man-A-Fre 24 gallon auxilliary tank

I just purchased the new Man-A-Fre 24 gallon Long Range auxiliary fuel tank and have had it installed. Apparently it is the first in the US. It is made by Longrange Automotive in OZ. My initial concern was the fit of the tank because of the 4x4 Labs rear bumper. The placement of the...

An aux tank with a transfer pump and twin filler necks in the same opening is perfect. I've heard nightmare stories about trying to replace the actual OEM tank and then having to deal with computers, emissions controls, etc.

rgsiii, I see on your ih8mud thread that you mentioned that it takes about 20 minutes to transfer the fuel from aux to main. Can you do this while driving?

I can't remember what type fuel pump used was back then. The inexpensive one that I replaced it with isfairly slow but keeps well ahead of your fuel usage while you are driving.
No problem filling main tank while driving. My install was on my 80 series LC was about 20 years ago. I have had to replace the pump and the gauge/switch. Relatively problem free.

I added an auxiliary fuel tank to my 80 series Land Cruiser and like it. It required moving the spare tire, a rear bumper to hold the tire, a fuel gauge/switch to power the pump and a new filler neck. A lot of work but it has been in for many years and still functions well. I can carry enough fuel to turn it into a really long range vehicle.

I think with the the GX550, I might be hesitant to do it until the warranty is over. If an engine issue ever came up, they will blame it on the fuel tank.

I am considering the same, wait for warranty to expire then do this type of mod, ARB offer similar rear bumper mounted wheel mounts which frees up the space for the 30 litre aux tank, LC 250 offers this option from new on some models so I don’t see it being an issue next year for GX if there is demand as they are built on the same platform.
