I understand that the LC Prado 150 come with two fuel tanks, main and aux. The aux tank goes where the spare tires is in the GX. My question is, can the LC 150 sub tank be added and plumbed to the GX 460? Did anyone do this before?

I am not worried about the spare tire, I can remove it or live without it.
Cheers,

You may want to reach out to Cruiser Brothers to see when 460 model will show up. They have one for the GX 470 that adds an additional 33 gallons.

Going to be cost-prohibitive unless you don't mind a big spend. Aftermarket tanks are very spendy, plus install. Plus the fact that there would likely have to be additional fab done if you don't have a GX-specific tank.

I looked into this awhile back casually and came up empty-handed. However if there was a way to fit the Prado subtank to the GX in an economical fashion I think that would be incredible. I'd love to have the 150L that the australians and ROW gets.

Since you're in Canada I'd look into what I could import under the 15 year rule.

I reached out to Ward Harris at Cruiser Brothers to see if we might see something for the 460 this year.

This last weekend did a ~400 mile trip with around 20.5 MPG... with a 33 gallon add-on giving 56 gallons of fuel that would give me a 1148 mile range.

Gotta love customer service at Cruiser Brothers. Ward got back to me right away.

They fully expect a solution for the 460 & 5th gen 4Rs this year.

You can buy the parts to install the OEM sub tank, including the filler neck and transfer hoses for less than most of the aftermarket options.

To get you started here is the tank part number 77001-60730
Tank straps 77601-60320 (you'll need 2)
Filler assembly 77210-60150
Sub Tank outlet assembly 77010-60240
Sub tank level sender 83320-60540
Main Tank pump holder with Sub inlet 77020-60470

There's a bunch of misc hardware and plumbing in the OEM setup but with a little ingenuity it shouldn't be hard.

I did some rough numbers as not all parts seems to be available in US but probably in the $1100 range shipped with list above.

I am sure someone can do for this number but depends on how much hack/modding one needs to do to know if it will be worth it.

In addition if they plan to do the work themselves or pay someone else.

Is 77001-60730 around the same capacity as well?

interesting
Are all of those parts necessary? Does anyone have a pic of such a system?
I dont really see how things like a sender, pump, etc are really needed just to increase capacity.
if the lowest part of the add on is lower than the original, then that could either mean you have suboptimal reserve not being used, or need a pump.
as long as you can get the lowest part of the new tank, and the outlet at about that level, then why not just a tank and two tubes?

Sub Tank is only 30L from what I read

The way most of the Toyota systems work is a transfer system (sub to main tank) and the engine feeds off the main tank only.
The fuel pump hangers have an extra nipple on them for the transfer feed.

I did a few of the factory sub tanks in the 80 series, it wasn't hard. We used a basic push button switch / relay with a Autometer gauge for the sub tank mounted in the center console cubby.

Acrad

So this sub-tank is only around 8 gallons (30L)?

I'm very unlikely to do this but I personally would want something more significant like the Cruiser Brother's model that would potentially have an additional 33 gallons (125L).

John00

yeah i saw some designs like that which basically refill the main tank with a pump. i dont know that it is necessary unless there are vacuum or overfill issues. either of those would mean that a pump/switch setup might be required.

i looked into it because i would like more capacity, one thing i found was this
https://forum.ih8mud.com/threads/gx4...trofit.933249/
the 1st post shows parts, and the 3rd mentions not needing the pump, etc. so it seems like my thought might be ok, but then above in this thread we have a list of parts which includes a sender.

Remember fuel weighs ~8 lbs. a gallon so a 33 gallon tank is ~250lbs of fuel plus the weight of the tank.

That's a lot of weight to stock at the tail end of the frame and outside the wheelbase.

Even though the GX is a great little pack mule, it's easy to be overweight by a bit even on a minimum build.

GVRW is 6600lbs, curb weight is 5305lbs
Extended tank (full) + Rear bumper (w/spare) 550lbs
Front bumper w/ winch 250lbs
Sliders 75lbs
Gear /water 150lbs
2 passengers 250-400lbs
=Overweight

8-9 gallons (almost half a main tank) gets you in the 400-500 miles per fill up range. That's more than enough for 99% of most trips wouldn't you agree?

John00

id be ok with an extra 9 gal if it only needs a tank and two tubes plus attaching. anything to fill up less frequently works for me.

Acrad

One has to remember what they plan to do with the relocated spare tire too.
